so I'm trying to pass the value of "x" here which will generate the random value.
<script>
var result = Math.random().toString(36).substring(2,5);
window.onload = function() {
document.getElementById("x").innerHTML=result;
}
</script>
I want to pass the value to my html code, in the mailto subject. so when people click the link, it will automatically open the default mail and send the email to info#legianbeachbali.com with the subject "Special Promotion + (random code)"
<p style="color: #5b5b5b; text-align: left; id: x;">
<a title="Book Now" href="mailto:info#legianbeachbali.com?subject=Special%20Promotion%20"+x>Book Directly with Us</a></p>
I tried to call the value on id and put "x" in the subject but as I expected, it doesn't work. could you guys please help me? I need to know how to show the value in the subject email.
Thanks in advance.
First remove + x from your HTML i.e, href attribute of your a tag.
Then add id to you a tag mailTo in this case (as shown below).
$(function() {
var result = Math.random().toString(36).substring(2,5);
var href = $("#mailTo").attr('href')
var newHref = href + result
$("#mailTo").attr("href", newHref)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a title="Book Now" id='mailTo' href="mailto:info#legianbeachbali.com?subject=Special%20Promotion%20">Book Directly with Us</a></p>

Background:
I'm coming from the server-side world of Rails, and trying to figure out the Netlify static html + serverless functions approach to doing a few extremely basic landing page web apps which need a serverless function to insert data into an HTML page.
I'm trying to start with the simplest possible case of an HTML page with a form and a serverless function that returns a result back to the page. (e.g., no static site generators).
I have not found any Netlify tutorials that show how a HTML page can have a form that posts to a function which then returns the result of that function back into the same web page.
The simplest sample app I can think of is a page asks a question, the user POSTs their answer to a serverless function, and the same HTML page is updated with the result of the function... a trivial case being to display "your answer was X" above the form. (It is immaterial to me whether the actual page is rewritten again with the result string included, or the result string is dynamically inserted by somehow poking the string to the div, so long as the result string originates in a serverless function; integrating serverless functions results with HTML pages is what I'm trying to learn.)
In the code below a simple HTML page below displays a form, the form POSTs an answer to a javascript function check_answer.js, and the javascript function erases the current page and displays the string "Your answer was XXXX".
That was simple to do, and lots of tutorials show how to have a function accept a form post then return a result string to the browser (overwriting the prior page).
My question:
How can the serverless function insert the result string back into the original HTML page (at the div id="answer") instead of outputting the result to a blank page?
Current code:
# index.html
<html>
<head>
<title>A test form</title>
</head>
<body>
<div id="answer">
</div>
<p>How much is 1 + 3?</p>
<p>form using POST:</p>
<form method="post" name="calc 2" action="/.netlify/functions/check_answer" id="calcform2" data-netlify="true" >
<p>
<label for="my_answer">Answer:</label>
<input type="text" name="my_answer" id="my_answer">
<label for="my_comment">Comment:</label>
<input type="text" name="my_comment" id="my_comment">
</p>
<p>
<input type="submit">
</p>
</form>
</body>
</html>
# functions/check_answer.js
exports.handler = async event => {
console.log(event.queryStringParameters);
console.log(event);
console.log(event.body);
if (event.httpMethod == 'POST')
{
console.log('is POST');
var params = parseQuery(event.body);
console.log(params);
var answer_string = params['my_answer'];
}
else
{
console.log('is GET');
var answer_string = event.queryStringParameters.my_answer || 'empty'
};
return {
statusCode: 200,
body: `Your answer was ${answer_string}`,
}
}
// handle parsing form query aaaa=bbbbb&cccc=dddd into hash object
// from https://stackoverflow.com/a/13419367/597992
function parseQuery(queryString) {
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
query[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
}
return query;
}
I want to send the value of textbox to the Action Method for searching the technology for that i want to get the value of textbox in Action.
I have the following code :-
#Html.TextBox("technologyNameBox", "", new { id = "technologyName", #class = "form-control", #placeholder = "Search For Technology" })
<span class="input-group-btn" style="text-align:left">
<a class="btn btn-default" id="searchTechnology"
href="#Url.Action("SearchTechnology", "Technology",
new {technologyName="technologyName",projectId=ProjectId })">
<span class="glyphicon glyphicon-search "></span>
</a>
</span>
Question :- How to get the value of textbox "technologyNameBox" in Action ?
Please help me out. Thanks in Advance!
You'd have to append the value to the URL via JavaScript before directing the user. Using jQuery (since that generally comes packaged with ASP.NET), it might look something like this (with a good bit of manual conditional checks for blank values or query string parameters):
$('#searchTechnology').click(function (e) {
e.preventDefault();
var url = '#Url.Action("SearchTechnology", "Technology", new { projectId=ProjectId })';
var technologyName = $('#technologyName').val();
if (technologyName.length < 1) {
// no value was entered, don't modify the url
window.location.href = url;
} else {
// a value was entered, add it to the url
if (url.indexOf('?') >= 0) {
// this is not the first query string parameter
window.location.href = url + '&technologyName=' + technologyName;
} else {
// this is the first query string parameter
window.location.href = url + '?technologyName=' + technologyName;
}
}
return false;
});
The idea is that when the user clicks that link, you would fetch the value entered in the input and append it to the URL as a query string parameter. Then redirect the user to the new modified URL.
On first sign I have the following code:
Accounts.onCreateUser(function(options,user){
if (typeof(user.services.facebook) != "undefined") {
user.services.facebook.picture = "http://graph.facebook.com/" + user.services.facebook.id + "/picture/?type=large";
}
return user;
});
Which results in the following URL string
http://graph.facebook.com/[myfacebookid]/picture/?type=large
Yet when it renders that url and returns
<img scr="http://graph.facebook.com/[myfacebookid]/picture/?type=large" alt="My Name">
All I see is a broken image. How can I pull this in so that it renders the facebook profile picture?
I use a helper function based off of the Facebook ID of the user to grab the image on the server. I notice my url has /picture? and your has /picture/? Hope this helps.
userPicHelper: function() {
if (this.profile) {
var id = this.profile.facebookId;
var img = 'http://graph.facebook.com/' + id + '/picture?type=square&height=160&width=160';
return img;
}
},
I don't know how I missed this before, but is this the src attribute on the image tag is actually written as scr:
<img scr=
Should be...
<img src=
You have http instead of https.
So:
"https://graph.facebook.com/" + id + "/picture/?type=large";
This was my problem.
Is there a way to use a different HTML markup to populate the caption text in a Nivo Slider? For search engines I don't want the content to be stuffed in the title attribute of the image tags.
Currently:
<img src="/image.jpg" title="Blah blah paragraph..." />
I would like something like this:
<img src="/image.jpg" /><div class="nivo-title">Blah blah paragraph...</div>
There's an easier way to do it.
NivoSlider supports HTML captions. See documentation here:
http://docs.dev7studios.com/jquery-plugins/nivo-slider
Set up your html caption in a div outside the #slider with display:none like this:
<div id="htmlcaption" class="nivo-html-caption" style="display:none">
<strong>This</strong> is an example of a <em>HTML</em> caption.
It even has a link.
</div>
Now, in your slide image set the title attribute to the id of the caption element:
<img src="images/slide2.jpg" alt="" title="#htmlcaption" />
When the slider runs, it finds the referenced caption and copies it to the active caption div and animates it for you. No need to change the javascript at all.
Open up your jquery.nivo.slider.js, on line 94 is the processCaption function. You can change this instead of looking at the 'title' attribute to anything you want.
For example
var processCaption = function(settings){
var nivoCaption = $('.nivo-caption', slider);
if(vars.currentImage.parent().find(".nivo-title").html() != '' && vars.currentImage.find(".nivo-title").html() != undefined){
var title = vars.currentImage.find(".nivo-title").html();
if(title.substr(0,1) == '#') title = $(title).html();
...
}
}
Thanks to Alexander for pointing me in the right direction! The following worked:
var processCaption = function(settings){
var nivoCaption = $('.nivo-caption', slider);
var nivoMyTitle = vars.currentImage.parent('.nivo-imageLink').find('.nivo-title'); //class of container with paragraph
if(nivoMyTitle.html() != '' && nivoMyTitle.html() != undefined){
var title = nivoMyTitle.html();
if(title.substr(0,1) == '#') title = $(title).html();
The HTML:
<img src="/image.jpg" /><div class="nivo-title">Blah blah paragraph...</div>
The CSS:
.nivo-title{display:none;} .nivo-caption p{font-size:12px;}
My question is similar to that one:
Dijit Menu (bar) with link
I'm using Dijit Menu as in following listing:
<div data-dojo-type="dijit/Menu">
<div id="menuItem" data-dojo-type="dijit/MenuItem">
urlLink
</div>
</div>
But link is not working as it blocked by dojo.stopEvent in _onClick().
The question is:
How to remove dojo.stopEvent and make link inside <div id="menuItem" data-dojo-type="dijit/MenuItem"> work properly?
The issue:
I need to put inside <div id=menuItem"> some code, which has to receive onClick event.
P.S. Originally this is XPages code.
Well I fell in same problem, saw this post and the related other, but wasn't satisfied with the "onclick" solution :
it didn't work (for me) with keyboard navigation
it imposes to a add script element (onclick=...) in the declarative zone which is not what I expect for unobtrusive JavaScript
Finaly I digged further in dojo and decided to directly use the href attribute of first sub-node in the handler. My script section (derived from dijit menus tutorial) is then :
<script>
require([
"dojo/dom",
"dojo/parser",
"dojo/dom-attr",
"dojo/query",
"dijit/registry",
"dijit/WidgetSet", // for registry.byClass
"dijit/Menu",
"dijit/MenuItem",
"dijit/MenuBar",
"dijit/MenuBarItem",
"dijit/PopupMenuBarItem",
"dojo/domReady!"
], function(dom, parser, domattr, query, registry){
// a menu item selection handler
var onItemSelect = function(event){
dom.byId("lastSelected").innerHTML = this.get("label");
var achild = query("a", this.domNode)[0];
if (achild != null) {
var href = domattr.get(achild, "href");
if ((href != null) && (href != '') && (href != '#')) {
window.location.href = href;
}
}
};
parser.parse();
var setClickHandler = function(item){
item.on("click", onItemSelect);
};
registry.byClass("dijit.MenuItem").forEach(setClickHandler);
registry.byClass("dijit.MenuBarItem").forEach(setClickHandler);
});
</script>
That way I don't have to change anything in a menu of type
<ul><li>...</li></ul>
that works with JavaScript disabled, and links work fine with mouse and keyboard navigation when JavaScript is enabled. Simply don't forget the "class='claro'" in body element ....
What about this:
<div data-dojo-type="dijit/Menu">
<div id="menuItem" data-dojo-type="dijit/MenuItem"
onclick="window.location('http://url.com')">
urlLink
</div>
</div>
