I download a JSON file, by example, saved and then open (all this by javascript), and want to access the Property 'Has_infobox_html', I tried to use the following loop

var poeItem = new function() {
    this._getHTMLdata = function(fileData) {
        for (i = 0; i = fileData.query.data.length; i++); {
            if (fileData.query.data[i] && fileData.query.data[i].property == 'Has_infobox_HTML') {
                return fileData.query.data[i].dataitem[0].item
            }
        }
    }
}

However it does not return anything, I tried to print the 'i’s and it seems to test only for 0 and then for, I have tested the other parts of the code and they work normally, the problem seems to be in this specific part

  • what you want to return? take care that when the if der true the return is breaking the for

There were two syntax errors in your script, very silly thing.

 for (i = 0; i =

The equals sign there causes an infinite loop. Use the <.

for (i = 0; i < fileData.query.data.length; i++); {

And it has a ; after the declaration of the loop.

Your corrected code:

 var poeItem = new function() {
     this._getHTMLdata = function(fileData) {
         for (var i = 0; i < fileData.query.data.length; i++) {
             if (fileData.query.data[i] && fileData.query.data[i].property == 'Has_infobox_HTML') {
                 return fileData.query.data[i].dataitem[0].item
             }
         }
     }
 }
