My application returns an array of array, where campanhas[] is an array of campanha[] which is also an array.
How can I make a foreach to fetch each campaign from within the campanhas array?
The array return of an array follows:
this.campanhas{campanha1{},campanha2{} ,campanha3{}}
You can make a loop type for(valor in array) that will get the value you want.
Example to get valor1 of each sub-array in campanhas :
var campanhas = {
campanha1: {
valor1: "a",
valor2: "b"
},
campanha2: {
valor1: "c",
valor2: "d"
},
campanha3: {
valor1: "e",
valor2: "f"
}
};
for(valor in campanhas){
console.log(campanhas[valor].valor1);
}I can suggest you use the native forEach of ECMAScript, but if you wanted to support old browsers, just include a simple polyfill in your application:
if ( !Array.prototype.forEach ) {
Array.prototype.forEach = function(fn, scope) {
for(var i = 0, len = this.length; i < len; ++i) {
fn.call(scope, this[i], i, this);
}
};
}
And use as follows:
function logArrayElements(element, index, array) {
console.log("a[" + index + "] = " + element);
}
[2, 5, 9].forEach(logArrayElements);
// logs:
// a[0] = 2
// a[1] = 5
// a[2] = 9
