Solution to JS string splicing error in IE_javascript skills

I haven’t used js for a long time, and I have forgotten a lot of stuff. Recently, I encountered a problem when splicing strings using JS. No matter how I spliced ​​it, an error was reported in IE, which was very frustrating.

A day later, I picked up the code and looked at it again. Suddenly I remembered the splicing of string escape characters in java, and then I remembered that js also has this stuff. " ";


No error is reported in the editor. No matter how to click onclick in the browser, it is not reflected. F12 reports an error. After reading the script, the string Completely transformed

tr = ""


is no problem.

The code is as follows:


onclick='confirmDelOneInfo("http://...?type=1&nodeId=11","Test 1");'


It can be seen that in html, if single quotes are used outside, they will be inside You must use double quotes, otherwise IE will report an error, so use the escape character " to convert double quotes. When dynamically generating HTML elements, pay special attention to the problem of single and double quotes, otherwise it will be a headache.
