问题描述
客户端正在使用Sharetribe,它允许您通过管理员添加自定义JS,但只能在头部。我希望我的脚本在jQuery之后加载,但jQuery加载到正文的末尾。文件加载后,如何编写添加主脚本的vanilla JS?
A client is using Sharetribe which allows you add custom JS via admin, but only in the head. I want my script to load after jQuery, but jQuery is loaded at the end of the body. How can I write vanilla JS that adds my main script to the end once the doc loads?
我尝试过:
<script>
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://cdn...";
document.body.appendChild(script);
var script2 = document.createElement("script");
script2.type = "text/javascript";
script2.text = "$(SOME.CODE.HERE);"
document.body.appendChild(script2);
</script>
但在文档加载完成之前(特别是在jQuery可用之前),它会被执行。我唯一可以想到的是设置一个计时器,但是这似乎很麻烦。
But it gets executed before the document is finished loading (and in particular, before jQuery is available). The only thing I can think of is to set a timer, but that seems buggy.
任何建议?
推荐答案
使用 DOMContentLoaded
事件:
document.addEventListener("DOMContentLoaded", function (event) {
console.log("DOM fully loaded and parsed");
// Your code here
});
DOMContentLoaded
与事件 jQuery
。
