查找并替换textarea中的所有匹配字符串
问题描述：
我有这个
var textarea=$('#content');
textarea.html(textarea.html().replace("PID","111111"));
这部分起作用，但是它只能在文本区域中找到第一个"PID"，并将其替换为"1111111".还有大约7个我也需要更改.我需要的是一种找到所有"PID"并将其替换为"111111"的方法.
This works partially, but it only finds the first "PID" within the textarea and replaces it to "1111111". There are about 7 others I need to change as well. What I need is a way to find ALL "PID" and replace it with "111111".
谢谢.

使用正则表达式替换字符串中所有出现的内容.试试这个
Use regex to replace all the occurrences in a string. Try this
textarea.html(textarea.html().replace(/PID/g,"111111"));
