How to Select Elements with IDs Containing Meta-Characters in jQuery?

Using Hashes in Element Selectors

When attempting to select an element using its ID attribute, challenges can arise when the ID contains meta-characters, such as hashes (#). In this instance, the following code will fail:

<code class="css">#test#1 {
    color: red;
}</code>

<code class="jQuery">$('#test#2').css('color','blue');</code>

To use meta-characters in an ID selector, they must be escaped with backslashes. Here's how to correct the issue:

<code class="css">#test\#1 {
    color: red;
}</code>

<code class="jQuery">$('#test\#2').css('color','blue');</code>

It's important to note that using # in ID attributes is not recommended, as it can lead to compatibility issues. Instead, it's preferred to use other characters that do not require escaping.

For example, consider the ID attribute "test.1." To select this element, you can escape the period as such:

<code class="css">#test\.1 {
    color: red;
}</code>
