How to solve the problem that the js assignment contains single quotes and double quotation marks

My page is a jsp page, which contains a parameter: lefttree,

This lefttree is spelled out from the background and contains html code: for example:
Copy codeThe Code is as follows:
<Div class = "test" onclick = "show ('tt1', 'abc')">

On the jsp page, you need to pay this value to a div using the js Code, as shown below:
Copy codeThe Code is as follows:
<Script type = "text/javascript">
Response response parent.doc ument. getElementById ('mptree '). innerHTML =' <% = lefttree %> ';
<Script>

In this way, because lefttree contains both single quotation marks and double quotation marks, the matching error with the single quotation marks at the outermost layer when values are assigned in js becomes:
Copy codeThe Code is as follows:
'<Div class = "test" onclick = "show ('tt1', 'abc')">'

Solution:

Escape Character "/"

When splicing lefttree in the background, it becomes the following form:

Copy codeThe Code is as follows:
<Div class = "test" onclick = "show (// 'tt1 // ', // 'abc //')">

Where:

The first two "//" are used to save a "/" on the page.

The third "/" is used to escape the single quotation marks.

In this way, the lefttree value in the webpage is:
Copy codeThe Code is as follows:
<Div class = "test" onclick = "show (/'tt1/',/'abc/')">
