[英]How to add javascript file in <head> in this condition?
Only if form
action is /?cms_mode=edit
仅当
form
操作是/?cms_mode=edit
<body id="home">
<form method="post" action="/?cms_mode=edit" id="main">
</form>
</body>
then a js file edit.js
should be added into head, otherwise not. 然后应该将js文件
edit.js
添加到head中,否则不会。
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="main.js"></script>
<script type="text/javascript" src="edit.js"></script>
</head>
Is it possible through jquery/javascript? 可以通过jquery / javascript吗?
And edit.js flie should be added after all other .js file 并且应该在所有其他.js文件之后添加edit.js flie
If you have to do it on the client-side in JavaScript, you may want to try the following: 如果您必须在JavaScript中在客户端执行此操作,则可能需要尝试以下操作:
var newScript;
if (document.getElementById('main').action.indexOf('?cms_mode=edit') >= 0) {
newScript = document.createElement('script');
newScript.type = 'text/javascript';
newScript.src = 'edit.js';
document.getElementsByTagName("head")[0].appendChild(newScript);
}
