如何检查脚本src匹配，然后重新分配src

Question

我需要检查每个script标记的src值，如果匹配，我想更改该脚本标记src属性......这样的事情：

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 {}
}} 

Answer 1

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

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