The read more button is not functioning properly when used in conjunction with the <br>

Can someone help me debug an issue I'm facing with my code? I have created an HTML tab that contains multiple DOM elements, each with a "Read More" button. Everything works fine when it's just plain text, but as soon as I add
tags within the paragraph, the button disappears. Any suggestions on why this is happening would be greatly appreciated. Thank you!

The problem can be observed in the first description of John Doe, which includes <br> tags.

var personArr = [];
var person = {["first-Name"]:"John", ["last-Name"]:"Doe", ["age"]:21, ["person-desc"]:"<br />Bacon ipsum dolor amet short loin doner tail meatloaf hamburger jerky <br />boudin picanha shankle turducken prosciutto cow kielbasa tenderloin. Jerky pork loin ham, pork turducken ham hock meatball...

Answer №1

When slicing a substring, make sure not to cut off the last character, as shown in this example where the final period is missing:

<br</span>&nbsp;&nbsp;<a href="" class="morelink" style="font-size:15px">Read More</a></span>

To correct this issue, adjust your code to include the last character when extracting substrings:

var c = content.substr(0, showChar); // Note that showChar is excluded
var h = content.substr(showChar, content.length - showChar); // Include it here

Ensure that the substring does not cut at a <BR> tag. Use caution when implementing these changes.

An alternative approach involves translating the DOM manipulation to jQuery. Pay attention to any potential issues introduced during tab handling due to additional data attributes.
