escaping special characters in javascript to use them in javascript

Question

I am using Javascript in my php application.I am stuck in one line\this is the line

'<td><input type="button" onClick="$(this).closest('tr').remove();" value="x" class="btn btn-primary"></td>'

I want to concatenate that ('tr') that is present with closest.

There is issue with double quotes and single quote.

We'll need more context. What is that string? Where? Is that in the PHP code or the JavaScript code? what does "concatenate that ('tr') that is present with closest" mean? — T.J. Crowder, Feb 16 '15 at 12:16
Use jQuery's `on` instead of 1990s style `onclick` attributes and it won't be an issue. — Quentin, Feb 16 '15 at 12:16
i think there is proble with double quote and single quotes that are used in that entire line and the problem is at ('tr') — Hemant Patil, Feb 16 '15 at 12:17
function addnewrow() { var n= ($('#inv-detail tr').length-0)+1; var row=''+ '' + n + ''+ ''+ ''+ '' ''; } — Hemant Patil, Feb 16 '15 at 12:21

you can normally escape quotes with backslash `\"` ie. `string = 'I\'m a "string"'` — MrPickles, Feb 16 '15 at 12:23

You are using single quote within a single quoted string. So you have to escape the quotes with \

echo '<td><input type="button" onClick="$(this).closest(\'tr\').remove();" value="x" class="btn btn-primary"></td>';

for javascript also it is the same

var x = '<td><input type="button" onClick="$(this).closest(\'tr\').remove();" value="x" class="btn btn-primary"></td>';
