Ajax XMLHttpRequest responsetext Return Value

In the past few days, a problem occurs, that is, the Chinese character string returned by responsetext can be normally displayed on the HTML page, but the same string cannot be matched in JS. The length is tested with length, they found that their length was very different, and finally found that the original returned value was initially "<Meta
Charset = "UTF-8"/> "is then the content displayed on the HTML page, so if you need to match the values equally, You Need To substr the returned values and truncate the previous ones.
VaR result = _ search_result.substr (25 );
// I have 25 characters before the return value. determine the length before the return value. You can use_ Search_result.length-the length of a Chinese character is displayed on the page (the result of the length of a Chinese character is 1)
