How do I loop through this JSON?

[tomharto]

The JSON that I get returned is this.

[{"name":"hpfa","addressLine1":"","addressLine2":"","town":"","county":"","postcode":"","contactName" :"","email":"","tel":"01442 766 285"},{"name":"hartford","addressLine1":"","addressLine2":"","town":"","county":"","postcode":"","co ntactName":"","email":"","tel":""},{"name":"hampshire","addressLine1":"","addressLine2":"","town":"" ,"county":"","postcode":"","contactName":"","email":"","tel":""}]

I need to loop through it and add each of the name elements to a javascript array. How would i do this?

a=[{"name":"hpfa","addressLine1":"","addressLine2":"","town":"","county":"","postcode":"","contactName" :"","email":"","tel":"01442 766 285"},{"name":"hartford","addressLine1":"","addressLine2":"","town":"","county":"","postcode":"","co ntactName":"","email":"","tel":""},{"name":"hampshire","addressLine1":"","addressLine2":"","town":"" ,"county":"","postcode":"","contactName":"","email":"","tel":""}]
names=[]
for(i in a)names.push(a[i].name)
alert(names)

since it is an array, I would advice to use a standard for() loop, not a for…in loop. anyways, there are also array methods to do the same.

PHP Code:

var a = [{"name":"hpfa","addressLine1":"", ... ];
var names = a.map(function(item) {
    return item.name;
});
