JSON.stringify（数据）

I have the following .ajax

$.ajax({

    url: urlpath,

    type: 'POST',

    dataType: 'json',

    data: JSON.stringify(json),

    contentType: 'application/json; charset=utf-8',

    success: function (data) {

        alert(JSON.stringify(data));

    },

    error: error

});

What I am passing back is a list with 3 columns. When I do alert(JSON.stringify(data)); it shows me the data - 3 columns and 4 rows of data. How do I go about parsing this and storing it into a table?

Say you have a table with an id="my-table", you can substitute your alert with something like:

   $('#my-table tr').each(function (r) {
        $('td', this).each(function (c) {
            // here you cycle on every td (column) of a row to populate it
            // example with 3 columns assuming this json structure 
            // {
                 "row1": [ 100, 200, 300],
                 "row2": [ 50, 200, 400 ],
                 "row3": [ 10, 300, 200]
            // }
            this.innerHTML = data["row"+r][c]
        })
    });

1. $('#my-table tr')... find create an array with your table rows
2. $('td', this)... apply an anonimous function on every td of the loop current tr (this acts as the search context for tds
