    <p>I agree with David Thomas, when he says that you should fix problem in the CSV generation script.</p> <p>But if you don't have control over that script, you can use <a href="http://www.w3schools.com/jsref/jsref_obj_regexp.asp" rel="nofollow">regular expressions</a> in the javascript <a href="http://www.w3schools.com/jsref/jsref_replace.asp" rel="nofollow"><code>replace()</code></a> to replace the first occurrence of a comma with an empty string (removing it):</p> <pre><code>", 111 , andro1 , developer ,".replace(/^,/, ''); </code></pre> <p>that returns:</p> <pre><code>" 111 , andro1 , developer ," </code></pre> <hr> <p><strong>Update:</strong></p> <p><a href="http://jsfiddle.net/UTkwX/" rel="nofollow"><strong>Here</strong></a> you can see a demo of a javacript that removes the first comma and justifies all columns to a predefined max width.</p> <p>Since you don't have a jQuery tag, I am assuming you want pure Javascript, but keep in mind that with jQuery would be much easier.</p> <p>The final output you can see from the demo, is</p> <pre><code> EmpID, EmpName, EmpTitle, 111, andro1, developer, 112, andro2, developer, 113, andro3, developer, </code></pre> <p>In this case I am right justifying each column to 10 characters.</p> <p>About the bold in columns title, that is not possible in CSV format, because CSV is a plain text format. You might consider for this <a href="http://www.python-excel.org/" rel="nofollow">xlwt</a>. </p> <p>Again, I agree that you should solve this formatting problem from the generating script, but if you are just the consumer of those files and want to fix them in javascript, then this solution should work for you.</p> <hr> <p><strong>Update 2</strong> You need to clean that javascript. Please read the regexp link that I included above.</p> <p>You can replace this:</p> <pre><code>a = a.replace(/&lt;\/td&gt;/g, ","); a = a.replace(/&lt;\/TD&gt;/g, ","); a = a.replace(/&lt;\/th&gt;/g, ","); a = a.replace(/&lt;\/TH&gt;/g, ","); </code></pre> <p>with simply this:</p> <pre><code>a = a.replace(/&lt;\/t(d|h)&gt;/gi, ''); </code></pre> <p>And why are you replacing <code>&lt;/tr&gt;</code> and <code>&lt;/TR&gt;</code> with <code>--newline--</code> and then again you replace <code>--newline--</code> with <code>\n</code>? You could simply do this in a single call:</p> <pre><code>a = a.replace(/&lt;\/tr&gt;/gi, '\\n'); </code></pre> <p>So, I think you end up having a single string with all csv content, where each row is separated by a <code>\n</code>. </p> <p><a href="http://jsfiddle.net/XSKHX/1/" rel="nofollow"><strong>Here</strong></a> is the updated script to handle this use case. I only changed the <code>var</code> declaration, the core remains the same.</p>

    1. COI don't see how jQuery would help in this simple text manipulation problem.

    2. COI pointed out jQuery, because its more elegant to use selectors than using `document.getElementById` and also `each()` loops. Its kind of hard to go back to pure Javascript once you start with jQuery. But I agree that my comment about jQuery, in this specific case, maybe was pointless.

    3. COThanks Jose.I will try this now.It would be useful for me if you could let me know how to use regular expression for each of the lines of the output CSV file. The reason is in the javascript I am using the whole output(the csv content as a whole) is stored in a variable.I would be great if I could iterate each of the lines and apply the regular expression. Also can you let me know how it is done in jquery.(I am pretty new to javascript and jquery)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
