I have this code
HashMap<String, List<String>> shopCat;
data goes like this:
shopCat => {"Vegetables":["Carrot",...], "Fruits":["Apple",....]}
model.addAttribute("shopCat", shopCat);
View code:
<tr th:each="sCat : ${shopCat}">
<tr th:each="sList: ${sCat.value}">
<tr th:each="item: ${sList}">
<td th:text="${item}"></td>
...
I get this error: Exception evaluating SpringEL expression: "sCat.value"
interestingly if I try to print key and value of sCat, it prints, but cannot iterate..
<tr th:each="sCat : ${shopCat}">
<td th:text="${sCat.key}"></td>
<td th:text="${sCat.value}"></td>
...
output:
Veg=[Carrot, Potato]
Fruits=[Apple, Melon]
Any idea where is this issue?

I want to get the list of IP from a website and add them into an array. The website shows the data like this:
<tbody><tr role="row" class="odd">
<td>131.108.216.44</td>
<td>47267</td>
<td>BR</td>
<td class="hm">Brazil</td>
<td>elite proxy</td>
<td class="hm">no</td>
<td class="hx">yes</td>
<td class="hm">2 minutes ago</td>
</tr>
<tr role="row" class="even">
<td>85.173.165.36</td>
<td>46330</td>
<td>RU</td>
<td class="hm">Russian Federation</td>
<td>elite proxy</td>
<td class="hm">no</td>
<td class="hx">yes</td>
<td class="hm">2 minutes ago</td>
</tr>
</tbody>
This is actually a very long list with 100's of table but the format is the same.
What I did is :
var c = new Crawler({
maxConnections: 1,
callback: function (error, res, done) {
if (error) {
console.log(error)
} else {
var $ = res.$;
$('tbody>tr>td').each((i, el) => {
const item = $(el)
console.log(item.text());
})
}
done();
}
})
c.queue({
uri: 'https://free-proxy-list.net/'
})
I want to keep the first 10 IPs from the website and add them into an array.
The first 10 would look like this:
let proxies = $('tr[role=row]').map((i, tr) => {
let host = $(tr).find('td:nth-child(1)').text()
let port = $(tr).find('td:nth-child(2)').text()
return `${host}:${port}`
}).get().slice(0, 10)
I'm building a webscraper with nodejs and pupeteer.
Everthing works fine, but now im stuck on how to get structured data from a table without classes. Here's an example:
I don't know how to iterate thru the table and extract the data in json format which should like this:
<table class="tableclass">
<tbody>
<tr>
<td>
<b>
<strong>
<span>A</span></strong> & B <strong><span>C</span></strong>Name</b>
</td>
<td >
Street No<br>
Zip City
</td>
<td >
Map | Website
</td>
</tr>
<tr>
<td>
<b>
<strong>
<span>A</span></strong> & B <strong><span>C</span></strong>Name</b>
</td>
<td >
Street No<br>
Zip City
</td>
<td >
Map | Website
</td>
</tr>
</table>
Obj ={
"content":[
{
"name":"A&B C Name",
"adress":[
"Street No",
"Zip",
"City"
],
"link":"http://www.websiteB.de"
},
]
}
Does the table have a consistent structure in each case? If so, you just need to figure out how to get to each element from the root of of table. For instance, to get the name, assuming that the above table structure is the same for all tables:
const table = document.querySelector('.tableclass')
Obj ={
"content":[
{
"name": table.querySelectorAll('tr')[0].querySelectorAll('td')[0].innerText;
....
]
}
Here, I get the table element I am interested in using document.querySelector('.tableclass') - which will return the first instance of .tableclass on the page. If you have multiple, you will have to use document.querySelectorAll and perform these operations on each table in a for-loop.
Then, I use the querySelector but limited to this table, and I grab the first element, because that's where the name is. (table.querySelectorAll('tr')[0]). Here I could have just used (table.querySelector('tr')) as I wanted the first element, but this is just to show you how you can access any of the s by their index. Finally, following the same logic, I need to select the first element as that is the element that contains all the 'name' text, then I just use its .innerText attribute to extract the text.
innerText will be your friend here - just traverse the DOM nodes using node.querySelector until you get to one that contains all the text you want and no more, then get the .innerText attribute on that node. If the table has consistent structure, you should just be able to figure this out for one table and it should work on all of them.
let data = await page.evaluate(() => {
var i = 0;
for (var i = 0; i < 5; i++) {
const table = document.querySelector('#tableclass');
let dealer = table.querySelectorAll('tr')[i].querySelectorAll('td')[0].innerText;
let adress = table.querySelectorAll('tr')[i].querySelectorAll('td')[1].innerText;
let link = table.querySelectorAll('tr')[i].querySelectorAll('td')[2].querySelectorAll('a')[1].getAttribute("href");
return {
dealer,
adress,
link
}
}
I want to loop thru the table/ each row in it. I know this is wrong, but I don't know how to loop in this case. Thanks for help!
I'm new to ASP and MVC so I'm learning. I'm trying to implement footable in my ASP.NET MVC 5 test project (I ultimately want to use the pagination and sorting features, but one step at a time).
I have added the .js files and .css files to the project and included them in the BundleConfig.cs file (see below). I'm not sure if that is all I need to do in order to use them in my project.
bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
"~/Scripts/bootstrap.js",
"~/Scripts/respond.js",
"~/Scripts/footable.min.js",
"~/Scripts/footable.js"));
bundles.Add(new StyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css",
"~/Content/footable.bootstrap.min.css",
"~/Content/footable.bootstrap.css"));
I'm retrieving data from a MySQL database and passing that to my view but I'm just getting a standard html table, what am I doing wrong ?
Here is the view code :-
#model IEnumerable<MVC5Footable.Models.radacct>
#{
ViewBag.Title = "Index";
}
<table class="footable">
<thead>
<tr>
<th>#Html.DisplayNameFor(model => model.username)</th>
<th>#Html.DisplayNameFor(model => model.framedipaddress)</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>#Html.DisplayFor(modelItem => item.username)</td>
<td>#Html.DisplayFor(modelItem => item.framedipaddress)</td>
</tr>
}
</tbody>
</table>
<!-- Initialize FooTable -->
<script>
jQuery(function ($) {
$('footable').footable();
});
</script>
Hoping someone can help. Thanks.
A little late, but for the record: you forgot to include the dot.
$('.footable').footable();
A question from a Jenkins beginnner.
Is it possible to create a kind of choice which sets multiple parameters for all stages? Currently I am only able to let the user choose each parameter value on its own.
Code:
pipeline {
...
parameters {
choice(
name : 'stage',
choices : 'DEV\nTEST\nQS\nPROD',
description : '''
<table>
<thead>
<tr>
<th>stage</th><th>nfs share name</th><th>swarm endpoint</th>
</tr>
</thead>
<tbody>
<tr><td>DEV</td> <td>DEV</td> <td>swarmid1</td></tr>
<tr><td>TEST</td><td>TEST</td><td>swarmid2</td></tr>
<tr><td>QS</td> <td>QS</td> <td></td></tr>
<tr><td>PROD</td><td>PROD</td><td></td></tr>
</tbody>
</table>
'''
)
****
SOME MAGIC SETTING THE PARAMETERS AS DESCRIBED IN THE DESCRIPTION

}
stages {
stage("do something") {
steps {
sh '''docker run ... ${MAGIC_NFS_SHARE} ...'''
}
}
}
}
I have a view with a table of products that can be added to a shopping cart. Each row has a DropDownList with allowed quantities that can be ordered along with a button to add to cart. Everything is populating and displaying properly. I know how to pass the item ID in the ActionLink but how can I get the value of the DownDownList associated with the table row of the ActionLink that was clicked?
I am guessing possibly using JQuery that fires when the ActionLink is clicked?
I also thought of making every row a form but that seems overkill.
Is there an easy MVC way to do this?
In prepping more info for a proper question and went ahead and solved it. Thank you Stephen for the nudge and info.
I tried putting a Html.BeginForm around each <tr> tag in the details section. This did indeed work for me. I was able to easily get the unique form info to POST for each individual row. However, when I would enable JQuery DataTables the submit would break. DataTables must be capturing the submit or click somehow. Haven't figured that out but it made me try JQuery which seems a much better way to do it.
Here is how I construct the table data row:
#foreach (var item in Model)
{
<tr>
<td>
<img src="#item.GetFrontImage()" width="100" />
</td>
<td>
<strong>#Html.DisplayFor(modelItem => item.DisplayName)</strong>
</td>
<td>
#Html.DisplayFor(modelItem => item.CustomerSKU)
</td>
<td>
#Html.DropDownList("OrderQty", item.GetAllowedOrderQuantities(), htmlAttributes: new { #class = "form-control" })
</td>
<td>
<a class="btn btn-default pull-right" data-id="#item.ID">Add to Cart</a>
</td>
</tr>
}
This creates a select with id of OrderQty and I embedded the item ID in data-id attribute of the link. I then used this JQuery to capture the info and POST it to my controller. Just have a test div displaying the results in this example:
// Add to Cart click
$('table .btn').click(function () {
// Gather data for post
var dataAddToCard = {
ID: $(this).data('id'), // Get data-id attribute (Item ID)
Quantity: $(this).parent().parent().find('select').val() // Get selected value of dropdown in same row as button that was clicked
}
// POST data to controller
$.ajax({
url: '#Url.Action("AddToCart","Shopping")',
type: 'POST',
data: JSON.stringify(dataAddToCard),
contentType: 'application/json',
success: function (data) { $('#Result').html(data.ID + ' ' + data.Quantity); }
})
});
The JQuery function receives the reference to the link being clicked so I can extract the Item ID from the data-id attribute. I can then get a reference to the dropdown (select) that is in the same row by using .parent.parent (gets me to the <tr> tag) and then just finding the next 'select' tag. Probably pretty obvious to a lot of you.
This works great for my purposes. I can also update other elements with data returned from the POST.
Thank you

for the table in html:
<div class="table-responsive">
<table id="employeeTable"class="table table-bordered">
<thead>
<tr>
<th class="text-center">ُُُEmpId</th>
<th class="text-center">Name</th>
<th class="text-center">Absense State</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td>#item.Id</td>
<td>#item.Name</td>
<td class="text-center">#Html.DropDownList("DDL_AbsentStatus", new SelectList(ViewBag.statusList, "Id", "Name"), new { #class = "form-control text-center" })</td>
</tr>
}
</tbody>
</table>
</div>
in javascript to get the selected value:
//Collect Date For Pass To Controller
$("#btn_save").click(function (e) {
e.preventDefault();
if ($.trim($("#datepicker1").val()) == "") {
alert("ادخل تاريخ يوم صحيح!")
return;
}
var employeesArr = [];
employeesArr.length = 0;
$.each($("#employeeTable tbody tr"), function () {
employeesArr.push({
EmpId: $(this).find('td:eq(0)').html(),
EntryDate: $.trim($("#datepicker1").val()),
StatusId: $(this).find('#DDL_AbsentStatus').val()
});
});
$.ajax({
url: '/Home/SaveAbsentState',
type: "POST",
dataType: "json",
data: JSON.stringify(employeesArr),
contentType: 'application/json; charset=utf-8',
success: function (result) {
alert(result);
emptyItems();
},
error: function (err) {
alert(err.statusText);
}
});
})
