To disable the selective check box on page load jquery
Question
I have a problem and search for this a while but , didnt get any soultion.
i have a page like:
<!doctype html>
<html>
<body>
<table id='mytable'>
<tr>
<thead>
<th><input type="checkbox" id="action-toggle" /></th>
<th>Institute</th>
<th>Version</th>
</tr>
</thead>
<tbody>
<tr class="row1"><td><input type="checkbox" class="action-select" value="119" name="_selected_action" /></td>
<td>ABCD Engineering College</td>
<td>1.0</td></tr>
<tr class="row1"><td><input type="checkbox" class="action-select" value="119" name="_selected_action" /></td>
<td>EFGH Engineering College</td>
<td>2.0</td></tr>
<tr class="row1"><td><input type="checkbox" class="action-select" value="119" name="_selected_action" /></td>
<td>IJKL Engineering College</td>
<td>1.0</td></tr>
</tbody>
</body>
</html>
jQuery(document).ready(function($){
jQuery("#result_list tbody tr").each(function(index,el){
val=$(el).text();
(if val=='1.0'){
$("el:contains('1.0')").closest("td").find("input.action-select").attr('disabled','disabled');
}
});
});
jQuery(document).ready(function($){
jQuery("#result_list tbody tr").each(function(index,el1){
$(el1).each(function(idex,el2){
val=$(el2).text();
(if val=='1.0'){
$("el:contains('1.0')").closest("td").find("input.action-select").attr('disabled','disabled');
}
});
});
Now i want in tbody where there is version 1.0 its respective check box should get disable on page load. I applied the .each function and two .each function as well but did not get the desired result. I would be really very helpful if could answer this .Thanks in Advance.

jQuery(document).ready(function($){
jQuery("#mytable tr").each(function(){
var version=$(this).find('td:last').text();
if (version === "1.0"){
$(this).find("input[type='checkbox']").attr('disabled','disabled');
}
});
});

also include </table> in your html code

Try this: http://jsfiddle.net/nvn6J/
$('#mytable tbody tr').each(function() {
var row = $(this);
if($(this).find('td:last').text() == '1.0') {
$(row).find('input[name="_selected_action"]').prop('disabled', 'disabled');
}
});
This works, but I believe this is best solved by disabling the options from the back end. I have no idea what your back-end code looks like or even if you're using PHP, but this is an example of what I'm talking about:
$counter = 1;
foreach($colleges_array as $College) {
echo '
<tr class="row' . $counter . '">
<td><input type="checkbox" class="action-select" value="' . $College->id . '" name="_selected_action" ' . ($College->version == '1.0' ? ' disabled="disabled' : '') . ' /></td>
<td>' . $College->name . '</td>
<td>' . $College->version . '</td>
</tr>';
$counter++;
}

Got it: http://jsfiddle.net/QUVjZ/1/
$("#mytable tr td").each(function(index, el1) {
val = $(el1).html();
if (val == '1.0') {
$(el1).parent("tr").find("td:eq(0) input[type='checkbox']").attr("disabled", "disabled");
}
});

A good implementation would be to use custom data attributes available in HTML.
Set the data attribute to the input boxes
<input type="checkbox" class="action-select" value="119"
name="_selected_action" data-version='1.0' />
Notice a new attribute added to the checkbox data-version='1.0'
Your Table will look like the following:
<html>
<body>
<table id='mytable'>
<tr>
<thead>
<th><input type="checkbox" id="action-toggle"/></th>
<th>Institute</th>
<th>Version</th>
</tr>
</thead>
<tbody>
<tr class="row1">
<td><input type="checkbox" class="action-select" value="119" name="_selected_action" data-version="1.0"/></td>
<td>ABCD Engineering College</td>
<td>1.0</td>
</tr>
<tr class="row1">
<td><input type="checkbox" class="action-select" value="119" name="_selected_action" data-version="2.0"/></td>
<td>EFGH Engineering College</td>
<td>2.0</td>
</tr>
<tr class="row1">
<td><input type="checkbox" class="action-select" value="119" name="_selected_action" data-version="1.0"/></td>
<td>IJKL Engineering College</td>
<td>1.0</td>
</tr>
</tbody>
</body>
</html>
and use the following jquery implementation on the document.ready to do it.
$(document).ready(function(){
$('input:checkbox[data-version="1.0"]').attr('disabled','disabled');
});
This is a cleaner implementation than looping through the objects
You can refer to using custom data attributes from here for example
An example of the same is available at the below URL:
And if you would like to make this functionality more generic, you can as well try this.
$(document).ready(function() {
function disableVersion(version) {
$('input:checkbox[data-version="' + version + '"]').attr('disabled', 'disabled');
}
disableVersion('1.0');
});
