Ellipsis in Text: Achieving the Mac Style
Challenge:
Implement ellipsis ( "...") in the middle of text within a resizable element. The ellipsis should disappear when the element width matches the full text width.
Solution:
-
Add Data Attribute to HTML:
In the HTML, include the full text value in a custom data-* attribute, such as:
<span data-original="your string here"></span>
-
JavaScript Event Listeners:
Add event listeners to the load and resize events of the element. These listeners should trigger a JavaScript function that will:
- Retrieve the original text from the data-* attribute
- Place the text in the innerHTML of the span element
-
Ellipsis Function:
Create an ellipsis function that trims the text if it exceeds a certain length. For example:
<code class="javascript">function start_and_end(str) { if (str.length > 35) { return str.substr(0, 20) + '...' + str.substr(str.length-10, str.length); } return str; }</code>
Customize the text length and position values as needed.
-
Tooltip for Full Text:
For added accessibility, consider adding an abbr-tag on the ellipsis with a tooltip that displays the full text:
<code class="html"><abbr title="full string">...</abbr></code>
