Basically I am trying to make a permalink from an event name. When I get the value from the event name using v-model it works but how do I put the converted permalink back in another input box in pug?
This works:
"P {{message}}",textarea(rows="2") {{message}}
but when i try the following:
input(value="{{message}}"),input(value={{message}}),input(value=#{{message}}),input(value=#{{message}}),input(value=#{message})
Pug does not render it & shows an indent error.
My question is how do I bind or reference data from Vue in input values ?
Pug template:
.col-md-12(style="padding:0px;")
.col-md-2.labelcont
label.labeltext Event Name :
.col-md-10
input(
type="text"
class="form-control"
placeholder="Event Name"
v-model="eventname"
)
.col-md-12(style="padding:0px;")
.col-md-2.labelcont
label.labeltext Permalink :
.col-md-10
textarea(
type="text"
class="form-control"
placeholder="Event Permalink"
) {{eventpermalink}}
Vue.js code:
var basicinfo = new Vue({
el: '#basic',
data: {
eventname: '',
eventpermalink: '',
}
})
basicinfo.$watch('eventname', function (newValue, oldValue) {
basicinfo.eventpermalink = basicinfo.eventname.replace(/[^a-zA-Z0-9 ]/g,'').replace(/ +/g,'-').toLowerCase();
})
You can use the v-bind directive. This way, you can bind any HTML element's attribute to a value whether it's calculated or a reference to your props or data.
In your case, it would be something like this:
input(type="text" class="form-control" placeholder="Event Name"
v-model="eventname" v-bind:value="YOUR-DATA-OR-WHATEVER")
Look the official documentation for further reading:

Well My purpose is to use checkbox to pick a template,after that it will be added to a database
but when i try to get the code of template into value it always display undefined.
Interface
Html Code:
<input type="checkbox" id="templatepick" name="picker" value="item.templatebodyclient" (change)="displaydata($event)">
templatebody attribut have the html of our template so i tried to get it from the checked template value to be set in database
Typescript code:
displaydata(event: { checked: any; }){
console.log("",event.checked) }
Any idea how i can solve this ? or another idea could be useful and thanks
You may use:
HTML
<input type="checkbox" id="templatepick" name="picker" [value]="item.templatebodyclient" (change)="displaydata($event)">
TS
displaydata(event: any) {
console.log(event.currentTarget.checked)
console.log(event.target.checked)
}
I'm trying to display the info of the user when I get the id using $routeParams.id, I already displayed the user's info using texts only but how can I display the user's image using img src?
In my controller I did this to get the selected user.
.controller('editbloodrequestCtrl', function($scope,$routeParams, Bloodrequest) {
var app = this;
Bloodrequest.getBloodrequest($routeParams.id).then(function(data) {
if (data.data.success) {
$scope.newLastname = data.data.bloodrequest.lastname;
$scope.newFirstname = data.data.bloodrequest.firstname;
$scope.newImg = data.data.bloodrequest.img;
app.currentUser = data.data.bloodrequest._id;
} else {
app.errorMsg = data.data.message;
}
});
});
Now that I get the users info, I displayed this in my frontend
<label>Lastname:</label>
<input class="form-control" type="text" name="lastname" ng-model="newLastname">
<label>Firstname:</label>
<input class="form-control" type="text" name="firstname" ng-model="newFirstname">
<label>Image:</label>
<img src ="" name="img" ng-model="newImg"> //how can I display the image here?
Sample Documents:
{firstname:"James",lastname:"Reid",img:"random.jpg"}
My output:
No need to bind ng-model to your image, just use the src with the absolute path of the image
<img src ="{{newImg}}" name="img">
No need to bind ng-model to your image, just use the src with the absolute path of the image..ng-model using only input tags.
<img ng-src ="newImg" name="newimg" />
I am trying to created a nested repeater or a nested list view using WinJS 4.0, but I am unable to figure out how to bind the data source of the inner listview/repeater.
Here is a sample of what I am trying to do (note that the control could be Repeater, which I would prefer):
HTML:
<div id="myList" data-win-control="WinJS.UI.ListView">
<span data-win-bind="innerText: title"></span>
<div data-win-control="WinJS.UI.ListView">
<span data-win-bind="innerText: name"></span>
</div>
</div>
JS:
var myList = element.querySelector('#myList).winControl;
var myData = [
{
title: "line 1",
items: [
{name: "item 1.1"},
{name: "item 1.2"}
]
},
{
title: "line 2",
items: [
{name: "item 2.1"},
{name: "item 2.2"}
]
}
];
myList.data = new WinJS.Binding.List(myData);
When I try this, nothing renders for the inner list. I have attempted trying to use this answer Nested Repeaters Using Table Tags and this one WinJS: Nested ListViews but I still seem to have the same problem and was hoping it was a little less complicated (like KnockOut).
I know it is mentioned that WinJS doesn't support nested ListViews, but that seems to be a few years ago and I am hoping that is still not the issue.
Update
I was able to get the nested repeater to work correctly, thanks to Kraig's answer. Here is what my code looks like:
HTML:
<div id="myTemplate" data-win-control="WinJS.Binding.Template">
<div
<span>Bucket:</span><span data-win-bind="innerText: name"></span>
<span>Amount:</span><input type="text" data-win-bind="value: amount" />
<button class="removeBucket">X</button>
<div id="bucketItems" data-win-control="WinJS.UI.Repeater"
data-win-options="{template: select('#myTemplate')}"
data-win-bind="winControl.data: lineItems">
</div>
</div>
</div>
<div id="budgetBuckets" data-win-control="WinJS.UI.Repeater"
data-win-options="{data: Data.buckets,template: select('#myTemplate')}">
</div>
JS: (after the "use strict" statement)
WinJS.Namespace.define("Data", {
buckets: new WinJS.Binding.List([
{
name: "A",
amount: 5,
lineItems: new WinJS.Binding.List( [
{ name: 'test item1', amount: 50 },
{ name: 'test item2', amount: 25 }
]
)
}
])
})
*Note that this answers part of my question, however, I would really like to do this all after a repo call and set the repeater data source programmatically. I am going to keep working towards that and if I get it I will post that as the accepted answer.
The HTML Repeater control sample for Windows 8.1 has an example in scenario 6 with a nested Repeater, and in this case the Repeater is created through a Template control. That's a good place to start. (I discuss this sample in Chapter 7 of Programming Windows Store Apps with HTML, CSS, and JavaScript, 2nd Edition, starting on page 372, or 374 for the nested part.)
Should still work with WinJS 4, though I haven't tried it.
Ok, so I have to give much credit to Kraig because he got me on the correct path to getting this worked out and the referenced book Programming Windows Store Apps with HTML, CSS, and JavaScript, 2nd Edition is amazing.
The original issue was a combination of not using templates correctly (using curly braces in the data-win-bind attribute), not structuring my HTML correctly and not setting the child lists as WinJS.Binding.List data source. Below is the final working code structure to created a nested repeater when binding the data from code only:
HTML:
This is the template for the child lists. It looks similar, but I plan on add more things so I wanted it separate instead of recursive as referenced in the book. Note that the inner div after the template control declaration was important for me.
<div id="bucketItemTemplate" data-win-control="WinJS.Binding.Template">
<div>
<span>Description:</span>
<span data-win-bind="innerText: description"></span>
<span>Amount:</span>
<input type="text" data-win-bind="value: amount" />
<button class="removeBucketItem">X</button>
</div>
</div>
This is the main repeater template for the lists. Note that the inner div after the template control declaration was important for me. Another key point was using the "winControl.data" property against the property name of the child lists.
<div id="bucketTemplate" data-win-control="WinJS.Binding.Template">
<div>
<span>Bucket:</span>
<span data-win-bind="innerText: bucket"></span>
<span>Amount:</span>
<input type="text" data-win-bind="value: amount" />
<button class="removeBucket">X</button>
<div id="bucketItems" data-win-control="WinJS.UI.Repeater"
data-win-options="{template: select('#bucketItemTemplate')}"
data-win-bind="winControl.data: lineItems">
</div>
</div>
</div>
This is the main control element for the nested repeater and it is pretty basic.
<div id="budgetBuckets" data-win-control="WinJS.UI.Repeater"
data-win-options="{template: select('#bucketTemplate')}">
</div>
JavaScript:
The JavaScript came down to a few simple steps:
Getting the winControl
var bucketsControl = element.querySelector('#budgetBuckets').winControl;
Looping through the elements and making the child lists into Binding Lists - the data here is made up but could have easily came from the repo:
var bucketsData = selectedBudget.buckets;
for (var i = 0; i < bucketsData.length; i++) {
bucketsData[i].lineItems =
new WinJS.Binding.List([{ description: i, amount: i * 10 }]);
}
Then finally converting the entire data into a Binding list and setting it to the "data" property of the winControl.
bucketsControl.data = new WinJS.Binding.List(bucketsData);
*Note that this is the entire JavaScript file, for clarity.
(function () {
"use strict";
var nav = WinJS.Navigation;
WinJS.UI.Pages.define("/pages/budget/budget.html", {
// This function is called whenever a user navigates to this page. It
// populates the page elements with the app's data.
ready: function (element, options) {
// TODO: Initialize the page here.
var bindableBuckets;
require(['repository'], function (repo) {
//we can setup our save button here
var appBar = document.getElementById('appBarBudget').winControl;
appBar.getCommandById('cmdSave').addEventListener('click', function () {
//do save work
}, false);
repo.getBudgets(nav.state.budgetSelectedIndex).done(function (selectedBudget) {
var budgetContainer = element.querySelector('#budgetContainer');
WinJS.Binding.processAll(budgetContainer, selectedBudget);
var bucketsControl = element.querySelector('#budgetBuckets').winControl;
var bucketsData = selectedBudget.buckets;
for (var i = 0; i < bucketsData.length; i++)
{
bucketsData[i].lineItems = new WinJS.Binding.List([{ description: i, amount: i * 10 }]);
}
bucketsControl.data = new WinJS.Binding.List(bucketsData);
});
});
WinJS.UI.processAll();
}
});
})();
I have installed meteor-typeahead via npm. https://www.npmjs.org/package/meteor-typeahead
I have also installed
meteor add sergeyt:typeahead
from https://atmospherejs.com/sergeyt/typeahead
I am trying to get the data-source attribute example to function so I can display a list of countries when the user begins to type. I have inserted all countries into the collection :-
Country = new Meteor.Collection('country');
The collection is published and subscribed.
When I type into the input field, no suggestions appear. Is it something to do with activating the API? if so how do I do this? Please reference the website https://www.npmjs.org/package/meteor-typeahead
My form looks like this:
<template name="createpost">
<form class="form-horizontal" role="form" id="createpost">
<input class="form-control typeahead" name="country" type="text" placeholder="Country" autocomplete="off" spellcheck="off" data-source="country"/>
<input type="submit" value="post">
</form>
</template>
client.js
Template.createpost.helpers({
country: function(){
return Country.find().fetch().map(function(it){ return it.name; });
} });
In order to make your input to have typeahead completion you need:
Activate typeahead jQuery plugin using package API
Meteor.typeahead call in template rendered event handler.
Meteor.typeahead.inject call to activate typeahead plugin for elementes matched by CSS selector available on the page (see demo app).
Write 'data-source' function in your template understandable by typeahead plugin. It seems your 'data-source' function is correct.
Add CSS styles for typeahead input(s)/dropdown to your application. See example here in demo app.
Try this way in your template:
<input type="text" name="country" data-source="country"
data-template="country" data-value-key="name" data-select="selected">
Create template like country.html (for example /client/templates/country.html) which contains:
<template name="country">
<p>{{name}}</p>
</template>
In your client javascript:
Template.createpost.rendered = function() {
Meteor.typeahead.inject();
}
and
Template.createpost.helpers({
country: function() {
return Country.find().fetch().map(function(it){
return {name: it.name};
});
},
selected: function(event, suggestion, datasetName) {
console.log(suggestion); //or anything what you want after selection
}
})
I come back with a symfony2 problem I have.
I'm trying to make a really simple "search form" to display some posts of a blog. To not overkill it, I've decided to create the form directly in the twig like this:
<form class="form-search" method="post" action="{{ url('search_route') }}">
<input type="text" placeholder="Search" class="input-medium search-query" name="search">
<button type="submit"><img src="/img/search.png" alt="search" /></button>
</form>
In my controller I'm trying to find a way of how to pass the value of the input in my query. Here is the code of the searchAction():
use Symfony\Component\HttpFoundation\Request;
/..
public function searchAction(Request $request)
{
$data = $request->request->all();
$dql = "SELECT a FROM PfBlogBundle:Article a WHERE a.title LIKE '{$data['search']}' ORDER by a.id DESC";
$query = $em->createQuery($dql);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$query,
$this->get('request')->query->get('page', 1)/*page number*/,
4/*limit per page*/
);
return $this->render('PfBlogBundle:Default:blog.html.twig', array('pagination'=>$pagination));
}
the fact is that if I print_r($data), I have the value sent through the input.. My problem is really to pass it in the query I think.. I'm developing locally and get a server error in the browser when I hit submit :/
Any idea?
