Best way to convert this or any build-in method for this conversion using JQuery.

9"Best way to convert this or any build-in method for this conversion using JQuery." Write code looping through the properties of the object and building up the result. There isn't a shortcut.– T.J. CrowderCommented Nov 28, 2012 at 11:42

Your mapping isn't that well defined. Please provide a few more examples and/or elaborate.– Asad SaeeduddinCommented Nov 28, 2012 at 11:50

Try this Code,
obj = {'a':['hello', 'hie'], 'b':['World', 'India']}
var key = Object.keys(obj);
array = [];
for (var i = 0; i < obj['a'].length; i++){
o = {}
for (k in key){
o[key[k]] = obj[key[k]][i]
}
array.push(o)
}

1Don't use a for-in-loop for the
keyarray. Also, some semicolons would be nice.– BergiCommented Nov 28, 2012 at 12:46
var obj = {'a':['hello', 'hie'], 'b':['World', 'India']};
var array = [];
for (var prop in obj)
for (var i=0; i<obj[prop].length; i++) {
var o = array[i] || (array[i] = {});
o[prop] = obj[prop][i];
}
No jQuery needed. With jQuery, it might look like this:
var array = [];
$.each(obj, function(prop) {
$.each(this, function(i) {
var o = array[i] || (array[i] = {});
o[prop] = this;
});
});
- slower and less readable. Do not use.
