将JSON作为参数传递给Javascript方法

Question

I am new to Javascript. I am writing a Java code which internally write code to call predefined Javascript method.

I have a Javascript method defined as:

  function myfunction(url, params) {
        $.post(url, params);
  }

This send params which is a JSON to the URL as post (I suppose).

My Java code generate HTML on the fly which internally generate something like:

<iframe onLoad="myfunction(myinternal, {"system":"abcdef", "token": "12345"})"> ......

However, this fails to run. Page inspection gave me:

SyntaxError: invalid property id
       myfunction(myinternal, {
                               ^

What did I do wrong here?

Many thanks

Answer 1

Your HTML has syntax errors. Should be more like this:

<iframe onLoad="myfunction(myinternal, {\"system\":\"abcdef\", \"token\": \"12345\"})">

or wrap in a single quote:

<iframe onLoad='myfunction(myinternal, {"system":"abcdef", "token": "12345"})'>

EDIT: (per first comment)

<iframe onLoad="myfunction(myinternal, {&quot;system&quot;:&quot;abcdef&quot;, &quot;token&quot;: &quot;12345&quot;})">

Answer 2

您需要在json对象中转义引号。

Answer 3

You used double quotes " in your JSON. They are interpreted by the HTML parser as the end of the onLoad attribute.

Try with single quotes, like this :

<iframe onLoad="myfunction(myinternal, {'system':'abcdef', 'token': '12345'})">
