How do query json for a value?

Mark Devid269612-Mar-2013

Hi!

How do I find out which "count"-id the loaded picture has?

The loaded picture is: "df5ddc27f7569f83e3867bec71a2cac0.jpg"
And my json are:

[
  {"count":1,"file":"8b6c5592f0378dc8c56e591a7b147826.jpg"},
  {"count":2,"file":"a44618c1afe93be486382ceb38536e02.jpg"},
  {"count":3,"file":"3c692942d69fba0d16971e0685f42757.jpg"},
  {"count":4,"file":"df5ddc27f7569f83e3867bec71a2cac0.jpg"}
]

Has anybody an idea for me?

Thanks in advance!

Hi Mark!

I assume that you are trying to do this with JavaScript

var jsondata = [
  {"count":1,"file":"8b6c5592f0378dc8c56e591a7b147826.jpg"},
  {"count":2,"file":"a44618c1afe93be486382ceb38536e02.jpg"},
  {"count":3,"file":"3c692942d69fba0d16971e0685f42757.jpg"},
  {"count":4,"file":"df5ddc27f7569f83e3867bec71a2cac0.jpg"}
];

function getId(file) {
    for(var f in jsondata) {
       if(jsondata[f].file == file)
         return jsondata[f].count;
    }
}

var id = getId("df5ddc27f7569f83e3867bec71a2cac0.jpg"); //count-id
