using jquery find('.classname') not working for locating TD elements? - javascript

I am traversing the divs on my page and looking up child elements using find and supplying a classname
select elements and input elements are located, but the 3 TDs I am trying to find are returning nothing
Here is the code snippet
$.each($(".ccypair"), function(index, element) {
var elements = {
selectElement : $(element).find('.selectstyle'),
inputElement : $(element).find('.inputstyle'),
tdElement1 : $(element).find('.decayTime'),
tdElement2 : $(element).find('.price.bidprice'),
tdElement3 : $(element).find('.price.offerprice')
};
});
Now the first two find() lines work fine, but the three tdElement ones below resolve to nothing. Anyone able to tell me where I am going wrong. I suspect for TD I need to have a different selector?
Apologies here is the html
<div class="ccypair" id="ccypairdiv_0">
<form>
<table>
<tr>
<td colspan="2" class="top currency"><select class="ccypairselect"/></td>
<td colspan="2" class="top volume"><input class="ccypairvolume" type="text" value="1m" autocomplete="off"/></td>
<td colspan="2" class="decaytime">00h:00m:00s</td>
</tr>
<tr>
<td colspan="3" class="price bidPrice">---.---</td>
<td colspan="3" class="price offerPrice">---.---</td>
</tr>
</table>
</form>
</div>
<div class="ccypair" id="ccypairdiv_1">
<form>
<table>
<tr>
<td colspan="2" class="top currency"><select class="ccypairselect"/></td>
<td colspan="2" class="top volume"><input class="ccypairvolume" type="text" value="1m" autocomplete="off"/></td>
<td colspan="2" class="top decaytime">00h:00m:00s</td>
</tr>
<tr>
<td colspan="3" class="price bidPrice">---.---</td>
<td colspan="3" class="price offerPrice">---.---</td>
</tr>
</table>
</form>
</div>
Thanks

First check if your jQuery is loading with the $, the try this
//think about structure, it makes your code more legible
$(".ccypair").each(function(index) {
var element = $(this); //each .ccypair found
var elements = {
selectElement : element.find('.selectstyle'),
inputElement : element.find('.inputstyle'),
tdElement1 : element.find('.decayTime'),
tdElement2 : element.find('.price.bidprice'),
tdElement3 : element.find('.price.offerprice')
};
});
cheers

As always a back to basics approach worked. A simple typo was the root cause here. Apologies
On that note. Does jQuery provide a flag so that rather than failing to locate an element and failing silently it will print out an error message. This would be really helpful?

Clone text from several elements to an a href as a mailto subject

I'm trying to append all the text in the td elements to the a element as the subject of the mailto link, but I can only get the first closest elements text. How do I make it so it retrieves the text from all the elements? If possible I would rather have the a link inside the tbody element instead of the tr wrapper.
HTML:
<tbody>
<tr class="row-2" role="row">
<td class="column-1" tabindex="0" style="">2238221D2</td>
<td class="column-2">HPINC</td>
<td class="column-3">N7P47AA</td>
<td class="column-4">HP USB 3.0 to Gigabit LAN Adapter</td>
<td class="column-5" style="display: none;">#4.2</td>
<td class="column-6" style="display: none;">16</td>
<td class="column-7" style="display: none;">30</td>
<td class="column-8" style="display: none;">52</td>
<a class="mailme" href="mailto:test#test.com?subject=Product request&body=">mailtolink</a>
</tr>
</tbody>
Script:
$('a.mailme').each(function() {
$(this).attr('href', $(this).attr('href') +
$(this).closest('a.mailme').prev('td').text());
});
Your code is almost right, just select all td-tags, get the text and join the resulting array:
$('a.mailme').each(function() {
$(this).attr('href', $(this).attr('href') +
$(this).closest('.row-2').children('td').slice(0,-1).map(function() {return $(this).html()}).get().join(','));
});
Working fiddle: https://jsfiddle.net/21873jcz/
EDIT My Solution will work if you fix your html code. a tags are not permitted within tr-tags. Only td or th elements are allowed. So please fix your html and it will work
I found a few problems but here is what you want:
https://jsfiddle.net/uqswr2k3/
var subject = "";
$(".row-2 td").each (function() {
subject = subject + '-' + $(this).html();
});
$(".mailme").attr('href', 'mailto:test#test.com?subject=' + subject + '&body=');
<table>
<tbody>
<tr class="row-2" role="row">
<td class="column-1" tabindex="0" style="">2238221D2</td>
<td class="column-2">HPINC</td>
<td class="column-3">N7P47AA</td>
<td class="column-4">HP USB 3.0 to Gigabit LAN Adapter</td>
<td class="column-5" style="display: none;">#4.2</td>
<td class="column-6" style="display: none;">16</td>
<td class="column-7" style="display: none;">30</td>
<td class="column-8" style="display: none;">52</td>
<a class="mailme" href="">mailtolink</a>
</tr>
</tbody>
</table>
Make sure the tbody has an outside table or it can cause issues with jQuery. You were setting the value of the subject to the current iteration and not collecting them all. I put a variable named subject to add each td cells' HTML content. I separated each value in the subject with a dash - to make it cleaner.

Get html with remove specific element on javascript/jquery

if my HTML is like this :
<tbody id="hasil-pencarian">
<tr>
<td align="center">1</td>
<td>TMS/IT/06/001</td>
<td>Erika Julia Widiyanti</td>
<td>Marketing</td>
<td>14-06-2015 13:59</td>
<td>14-06-2015 14:00</td>
<td>Erika test 1</td>
<td id="action" class="center" width="10px">
<a class="btn btn-success">
</td>
</tr>
</tbody>
I got all the html above like this :
var result = $("#hasil-pencarian").html();
But, How can I get all the HTML without the <td> with id='action' ?
Little confused. Any help will be so appreciated.
I think you could create clone then remove the element then get the content like
var result = $("#hasil-pencarian").clone().find('#action').remove().end().html();

Show rows in table with cells name attribute containing string from input (JQuery)

I would like to have keyup function that would show only rows matching the input text by cell that spans on multiple rows.
Consider following table:
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1'> dummy1 </td>
</tr>
<tr>
<td name='Key1'> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2'> dummy3 </td>
</tr>
<tr>
<td name='Key2'> dummy4 </td>
</tr>
</table>
jsfiddle
Here each row has second td tag with name that matches its "parent" column text. So when I type 'Key1' at the input field I would like it to show only dummy1 and dummy2. Is it possible in jquery?
I understand that you want to display the rows that has a matching name. If this is wrong, please elaborate more, then I can update it.
Here is a demo: https://jsfiddle.net/erkaner/gugy7r1o/33/
$('input').keyup(function(){
$('tr').hide();
$("td").filter(function() {
return $(this).text().toLowerCase().indexOf(keyword) != -1; }).parent().show().next().show();
});
});
Here's my take on your issue, assuming you always want the first column to show. https://jsfiddle.net/gugy7r1o/2/
<input type="text" id="myInput" />
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1' class="data"> dummy1 </td>
</tr>
<tr>
<td name='Key1' class="data"> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2' class="data"> dummy3 </td>
</tr>
<tr>
<td name='Key2' class="data"> dummy4 </td>
</tr>
</table>
.data{
display:none;
}
var theData = $('td.data');
var input = $('#myInput').on('keyup', function(){
theData.hide();
var value = input.val();
var matches = theData.filter('[name="'+value+'"]');
matches.show();
});
Firstly, I would recommend using <ul> to wrap each key in as tables should be used for data structure (Forgive me if that is what it is being used for).
Secondly, just attach an on keyup event to the search box and then find matches based on the id. See example below:
JS Fiddle Demo
It is also worth mentioning that it could be useful attaching a timeout to the keyup event if you end up having large amounts of rows so that only one filter is fired for fast typers!

Selecting content with JQuery

Any ideas why this doesn't work?
http://jsfiddle.net/zk4pc/2/
I'm trying to get it so that everytime there is an element with the class "insert_name", the name is printed from the table.
Could you also help me make the selection more advanced (for instance only using the data from the first tr in the "client-profile" class?
Thanks!
HTML
<body onload="printMsg()">
<div id="api_data" style="display:none;">
<div class="client-profile">
<div class="head icon-5">Customer Details</div>
<table id="client-information">
<tbody>
<tr>
<td class="left">Name:</td>
<td class="color">Matthew Tester
</td>
</tr>
<tr class="dark">
<td class="left">E-mail:</td>
<td class="color">asdfg</td>
</tr>
<tr>
<td class="left">Registration:</td>
<td class="color">2013-11-21</td>
</tr>
<tr class="dark">
<td class="left">Status:</td>
<td class="color"><span class="active">Active</span>
</td>
</tr>
<tr>
<td class="left">Last Login Time:</td>
<td class="color" title="2014-05-28 11:43:46">1 hour ago</td>
</tr>
<tr class="dark">
<td class="left">Last Login From:</td>
<td class="color">123.123.123.123</td>

<td class="left">Location:</td>
<td class="color">United Kingdom</td>

</div>
</div>
<div class="insert_name"></div>
</body>
Javascript
(function printMsg() {
var node = document.getElementsByClassName('insert_name');
node.innerHTML = $('[class*="color"]').eq(0).text();
})();
jsFiddle Demo
The issue is with your node selection. When you select by class name it returns an array of elements. Since you are only looking for the div with that class name, access the first index to reference it.
var node = document.getElementsByClassName('insert_name')[0];
edit
To make this iterate all of the nodes you could take this approach
var nodes = document.getElementsByClassName('insert_name');
var text = $('[class*="color"]').eq(0).text();
for(var i = 0; i < nodes.length; i++){
nodes[i].innerHTML = text;
}
Alternatively, since jQuery is already included, you could remove the body's onload event and just use this
jsFiddle Demo
$(function(){
$('.insert_name').html($('[class*="color"]').eq(0).text());
});
To ensure this only acts on the client-profile class the selector would be
$('.insert_name').html($('.client-profile [class*="color"]').eq(0).text());
If you are just trying to insert the name rather than all of the content, this should do the trick:
$(function() {
$('.insert_name').text($('td:contains("Name:")').next().text());
});
Here is the fiddle:
http://jsfiddle.net/b8LKQ/
Hope that helps!
I added a little more jQuery:
$(function() {
$('[class*="color"]').each(function(){
$('.insert_name').append($(this).text());
});
});

Hope that helps!

javascript jquery childnode

I have a problem that i want to access the normaltagCmt elements value:
<div id="random no">
<div id="normaltagdialog">
<table style="width:100%; height:100%" border="2px">
<tr style="width:100%; height:13%" align="left">
<td>
<label> {$LANG.TEXT}</label>
</td>
</tr>
<tr style="width:100%; height:59%; vertical-align:middle" align="center" >
<td>
<textarea id="normaltagCmt" style="width:90%; height:90%" ></textarea>
</td>
</tr>
<tr style="width:100%; height:13%">
<td>
<label> {$LANG.COLOR}</label>
</td>
</tr>
<tr style="width:100%; height:15%; ">
<td>
<table style="width:100%;height:100%" cellpadding="2" cellspacing="2">
<tr id="colorPad" align="center">
</tr>
</table>
</td>
</tr>
</table>
</div>
</div>
The script i have written above is a jquery dialog and this dialog opens many times.
i want to get the value of normaltagCmt for a particular div with a specific random id.
How can i get that in javascript?
Try $('#random_no #normaltagCmt').val().
i hope by "random no" you mean random number, you cant have a space in a ID and ill use ID14 instead of "random no".
$("#ID14 #normaltagdialog table tr td #normaltagCmt").val()
There can only be one of any ID in javascript, so you could just do $('#normaltagCmt') and it will always only return the one element.
However, if you want to check to make sure that it is a child of an element with a random id (a number that you do not know), then it will get a little trickier.
$("#normaltagCmt").filter(function() {
var valid_parent = false;
var numeric_re = /^\d+$/g;
for( var parent in $(this).parents("div") ) {
if( re.test(this.id) ) {
valid_parent = true;
break;
}
}
return valid_parent;
}
This bit of jQuery will test to make sure that the element with the specified id has a parent div with a numeric id. If it does not, then you will be left with an empty jQuery object.
