使用jQuery ajax调用Javascript函数

Question

Firstly let me preface this by saying I would never WANT to do this, nor do I intend to do this, I simply need to know if it is possible.

Considering that you can place "javascript:myFunction();" in a link's href attribute, is it possible to specify "javascript:myFunction();" as the url parameter in jQuery's $.ajax function?

Again, I know this would be counterintuitive and a pointless exercise for any production code. I am simply interested in whether it could theoretically be done.

Answer 1

You're free to pass that to "$.ajax()" as the URL, but it won't work. It's really an ugly old practice to use "javascript:" values for anchor tag "href" values too.

Answer 2

No this will not work as intended. The A element is special case, and using that string with jQ.ajax() will result in a bad URL.

Answer 3

No it does not work.

The javascript:myFunction() is something of a hack URL that you can put as the href of an anchor to link to a JS function.

$.ajax wants to make an HTTP request and will attempt to, with whatever URL you provide. In the case of a javascript:* URL, it will do nothing useful.

Answer 4

您可以将其放在url中，但“ javascript：”将成为url的一部分，因此当浏览器传输请求时，您可能会收到无法找到url路径的错误，它不会知道这是javascript。
