How to Handle Double Quotes Within JavaScript Strings?

Double Quotation Inclusion in JavaScript Strings

Enclosing a string within double quotes can pose challenges when it contains double quotes within its content. This situation arises often in programming, particularly when rendering HTML code. For example, consider the following JavaScript statement:

<code class="javascript">if (i == 0) {

   error +=  "<li> this is not the name "....." </li>\n"
}</code>

The requirement here is to include double quotes within the string. To accomplish this, you have two options:

Use Single Quotes

Instead of using double quotes to enclose the entire string, use single quotes. This allows you to include double quotes within the string without ambiguity.

<code class="javascript">error += '<li> this is not the name &quot;.....&quot; </li>\n';</code>

Escape Double Quotes

Another approach is to escape the double quotes within the string. This involves adding a backslash () before each double quote in the string.

<code class="javascript">error += "<li> this is not the name \".....\" </li>\n";</code>

Both of these methods effectively allow you to include double quotes within JavaScript strings and display them correctly in the browser.
