I have just this array :
var sArray = {856:"users", 857:"avatars", 858:"emails"};
and I want to use forEach
in a way to get key and value from that:
key = 856
value = user
My $.each
code doesn't return the result I'm expecting, and I get instead:
856:user
I must be separate that with :
to get key and value from this array.
My code is:
$.each(template_array, function(key, value) {
console.log("key: " + "value: " + value);
});
How to access key and value without separate?
Just take Object.keys
for the keys and Array.prototype.forEach
for the values in plain Javascript.
var sArray = { 856: 'users', 857: 'avatars', 858: 'emails'}; Object.keys(sArray).forEach(function (key) { document.write('key: ' + key + ', value: ' + sArray[key] + '<br>'); });
Just concatenate them using +
var template_array = { 856: 'users', 857: 'avatars', 858: 'emails' }; $.each(template_array, function(key, value) { console.log('key:' + key + ', value:' + value); });

UPDATE : I think you have an array then use the following code
var template_array = ['856: users', '857: avatars', '858: emails' ]; template_array.forEach(function(v) { v = v.split(':'); console.log('key:' + v[0] + ', value:' + v[1]); });
try this one
var template_array = {
856: 'users',
857: 'avatars',
858: 'emails'
};
var date = [];
$.each(template_array,function (key , val){
date.push({key:key, value:val})
});
console.log(date)
var template_array = { 856: 'users', 857: 'avatars', 858: 'emails' }; for (key in template_array) { console.log('key:' + key + ', value:' + template_array[key]); });
