如何检查脚本src匹配，然后重新分配src [英] How to check for script src match, then reassign src

问题描述

我需要检查每个脚本标签的src值，如果有匹配，我想更改脚本标签src属性......这样的事情：

I need to check every script tag's src value and if there is a match, I would like to change that script tags src attribute... Something like this:

var scripts = document.getElementsByTagName("script")[0].src

for (i=0;i<scripts.length;i++){
  if(scripts[i] == "something.js"){
    document.getElementsByTagName("script")[i].src = "this.js"
  }
  else {}
}} 

推荐答案

var scripts = document.getElementsByTagName("script");

for (i=0;i<scripts.length;i++){
  if(scripts[i].src == "something.js"){
    scripts[i].src = "this.js";
  }
}
