检索URL中编码的JSON

Question

I'm using JSON format to send some data between two pages. In the second page I need to get the JSON i have encoded in the URL to add some data in it and send it again to a 3rd page. this is the code I used to send the JSON using GET to the second page.

    form.submit( function(e) {
        // stop the regular form submission
        e.preventDefault();

        // collect the form data
        var data = {};

        data["valueDimensional"] = $('#valueDimensional').val();
        data["timeSlot"] = $('#timeSlot option:selected').val();
        data["splitOption"] = $('#splitOption option:selected').val()

        var strJSON = JSON.stringify(data);
        var escapedStrJSON = encodeURIComponent(strJSON);
        var url = "/warning/app/data?par="+escapedStrJSON;
        window.location.href = url;

     });

In the second page i tried this:

     form.submit( function(e) {
            // stop the regular form submission
            e.preventDefault();

            $.getJSON(window.location.href, function(data) {
                //data is the JSON string
                alert(data);
            });

        });

Answer 1

在第二页代码中使用JSON.parse(window.location.href)代替：

$.getJSON(window.location.href, function(data) {

Answer 2

getJSON takes a URL and makes an HTTP request to it.

It does not search through the URL in order to try to find something that looks like JSON encoded directly into it.

You need to:

1. parse the query string to read the value of par
2. Pass the result through JSON.parse .
