Body
copied!<p>I have a form where the <strong>name attributes get updated</strong>, but the problem is im using multidimensional values as follows:</p> <pre><code><input type="text" name="questions[0][question]" /> <input type="text" name="questions[0][order]" /> <input type="text" name="questions[0][active]" /> <input type="text" name="answers[0][1][answer]" /> <input type="text" name="answers[0][2][answer]" /> <input type="text" name="answers[0][3][answer]" /> <input type="text" name="questions[1][question]" /> <input type="text" name="questions[1][order]" /> <input type="text" name="questions[1][active]" /> etc... </code></pre> <p>I need to change the value within the square brackets with JavaScript no <strong>matter what position</strong> they are in. I have tried using the following regular expression to match the value between the square brackets: </p> <pre><code>/(?<=\[)[^\]]*(?=\])/g </code></pre> <p>but this matches all occurrences, and what I need to do is somehow find and replace the nth occurrence.</p> <p>Or if there is another way to find and replace the values within the square brackets without using regular expressions I'm all ears.</p> <p>Thanks in advance</p> <p><strong>Resolved</strong></p> <p>This final code is as follows:</p> <pre><code>$('input', this).each(function(){ var name = $(this).attr('name'); var i = 0; $(this).attr('name', name.replace(/\[.+?\]/g,function (match, pos, original) { i++; return (i == 1) ? "[THE REPLACED VALUE]" : match; })); }); </code></pre>
