JSON Problem - With Array

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?

You made a typo with the datatype

`dataType: "jason"`,

should be

`dataType: "json",`

It looks like you've got two issues:

  1. The JSON in your example is invalid. It should be [{…}, {…}, …] (noete the commas).
  2. Your jQuery call has "jason", not "json"

$.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"
    }
]

For future reference, a great resource is JSONLint.com which allows you to validate your JSON on the fly.
