Tips for Altering Information within a Text Box

Below is a snippet of HTML code that needs to be modified:

<td class="targetTD">
  <a href="http://foo.com">
    <span>content</span>
  </a>
  **Text I want to modify**
  <span>more content</span>
</td>

The targetTD class appears multiple times depending on the content being rendered. For each instance, there is a need to remove the substring ": " from the beginning of the text block. This substring is not within its own element and cannot be wrapped in an id/class. Trying out some JavaScript solution resulted in a console error:

Unable to get property 'replace' of undefined or null reference.

Solution Update

The following script provided by @Vaibhav resolved the issue:

<script type="text/javascript">

    $(function() {
        $('.targetTD').each(function () {
            $(this).html($(this).html().replace(/\:\s/g, ''));
        });
    });

</script>

Update 1

A fix suggested by @BenM helped eliminate the error message:

<script>
$(function() {
    $('.targetTD').html(function() { $(this).html().replace(': ', ''); });
});
</script>

Even though the above modification prevented the error, it did not successfully remove the ": " from the text block. Any insights into why this might be happening?

Update 2

In addressing a comment from @ElvisLikeBear, here are some SharePoint specific details:

  • The objective is to hide the column name in a grouped list. In SP2010, this was achieved by hiding the ms-gb class. However, in SP2013, the expand/collapse button is also associated with this class making wholesale hiding unfeasible. The span containing the column name has been successfully hidden (as mentioned in the code above), but the ": " still remains in the text block at the start of each category name.

  • The code is being implemented at the page level as a snippet using the Script Editor web part.

Answer №1

Hey Brendan, there's a small issue with your code - you're replacing the ':' with '' but not assigning it back to the same td.

The Replace(':','') function only replaces the first occurrence of ':'. Check out my code below which will replace all instances of ':'.

I suggest using a foreach loop to iterate over all the Tds, as "targetTD iterates a dynamic number of times depending on the content being rendered".

Here's the HTML snippet:

<table>
    <tr>
        <td class="targetTD">
            <a href="http://foo.com">
                <span>content</span>
            </a>
            Test:Test1
            <span>more content</span>
        </td>
    </tr>
    <tr>
        <td class="targetTD">
            <a href="http://foo.com">
                <span>content</span>
            </a>
            Test:Test1:test2
            <span>more content</span>
        </td>
    </tr>
    <tr>
        <td class="targetTD">
            <a href="http://foo.com">
                <span>content</span>
            </a>
            Test:Test1:test3:test4
            <span>more content</span>
        </td>
    </tr>
</table>

And here's the JQuery code:

<script type="text/javascript">

    $(function() {
        $('.targetTD').each(function () {
            $(this).html($(this).html().replace(/\:/g, ''));
        });
    });
    </script>

I've tested the script and it works perfectly!

Answer №2

Ensure that the DOM is fully loaded:

<script>
$(function() {
    $('.targetTD').html(function() { $(this).html().replace(': ', ''); });
});
</script>

Answer №3

It seems like your tag is indicating that the code is running on a SharePoint site, which may be why it's not functioning as expected. To ensure proper deployment for SharePoint, you'll need to take the appropriate steps.

You have several options for deploying your code, such as using a solution or feature. For smaller scripts that only need to run on one page, consider utilizing a script web part (known as the Content Editor web part in previous versions of SharePoint) or adding a code snippet directly onto the page in SharePoint 2013.

While another option is to insert the script into the <head> tag through SharePoint Designer, this method may not always be considered best practice, unless in specific scenarios where it makes sense (although it might be the easiest approach for developers unfamiliar with SharePoint).
