Question

Here is my JSON returned from a PHP file (just as a side note, I can use EITHER one):

// JSON Option #1:

[{“field”:”title_of_production_row”, “required”:”1″}{“field”:”where_released_row”, “required”:”1″}{“field”:”release_date_row”, “required”:”1″}{“field”:”running_time_row”, “required”:”1″}{“field”:”accepting_award_row”, “required”:”1″}{“field”:”contact_name_row”, “required”:”1″}{“field”:”promocode_row”, “required”:”0″}{“field”:”payment_method_row”, “required”:”1″}{“field”:”tbl_submit”, “required”:”0″}{“field”:”production_company_row”, “required”:”1″}]

// JSON Option #2:
{“title_of_production_row”:”1″,”where_released_row”:”1″,”release_date_row”:”1″,”running_time_row”:”1″,”accepting_award_row”:”1″,”contact_name_row”:”1″,”promocode_row”:”0″,”payment_method_row”:”1″,”tbl_submit”:”0″,”production_company_row”:”1″}

I want to loop through each field and required, and alert them. I’ve tried things like:

    $.ajax({
        url: './ajax/get_cat_info.php?cid=' + cid,
        dataType: "jason",
        async: false,
        success: function(html) {
            alert(html);

         $.each(html, function(key, val) {
            alert('key: ' + key + ' - val: ' + val);
         });

        }
    });

But this alerts individual characters. Any thoughts?

Answer 1

$.ajax({
    url: './ajax/get_cat_info.php?cid=' + cid,
    dataType: "json", // Need a correct dataType
    async: false,
    success: function(html) {
        alert(html);

     $.each(html, function(key, val) {
        alert('key: ' + key + ' - val: ' + val);
     });
    }
});

JSON Option 1 was invalid: Try this:

[
    {
        "field": "title_of_production_row",
        "required": "1"
    },
    {
        "field": "where_released_row",
        "required": "1"
    },
    {
        "field": "release_date_row",
        "required": "1"
    },
    {
        "field": "running_time_row",
        "required": "1"
    },
    {
        "field": "accepting_award_row",
        "required": "1"
    },
    {
        "field": "contact_name_row",
        "required": "1"
    },
    {
        "field": "promocode_row",
        "required": "0"
    },
    {
        "field": "payment_method_row",
        "required": "1"
    },
    {
        "field": "tbl_submit",
        "required": "0"
    },
    {
        "field": "production_company_row",
        "required": "1"
    }
]
