Creating an object out of a string in javascript

Question

I have a string:

var str = "username:joe_1987;password:123456;email:[email protected];"

Can I (or rather,) how can I create an object out of in a way that I can call it's parameters, something like:

alert(obj.password) and get 123456

Answer 1

I would recommend splitting on the semicolons in the string, giving you an array that will look like:

["username:joe_1987", "password:123456", "email:[email protected]"]

You can then apply the same idea to each element of this array, and then create the object. I've chucked a snippet below to explain:

var str = "username:joe_1987;password:123456;email:[email protected];"
var splitBySemiColon = str.split(";");
splitBySemiColon.pop(); //Remove the last element because it will be ""
var obj = {};
for(elem in splitBySemiColon) {
 splitByColon = splitBySemiColon[elem].split(":");
 obj[splitByColon[0]] = splitByColon[1];
}

Hope this helps!

I'm no expert, but something like this should work:

string = 'username:joe_1987;password:123456;email:[email protected];';
array = string.split(';');
object = {};
for(i=0;i<array.length;i++){
 if(array[i] !== ''){
 console.log(array[i]);
 object[array[i].split(':')[0]] = array[i].split(':')[1];
 }
}
console.log(object);

IF you're certain the desired values won't have ; or :, you can just

var str = "username:joe_1987;password:123456;email:[email protected];"
var obj = {};
str.split(';').forEach( function(segm) {
 if(segm.trim()) { // ignore empty string
 var spl = segm.split(':');
 obj[ spl[0] ] = spl[1];
 }
})

Answer 4

use this

 var str = "username:joe_1987;password:123456;email:[email protected];"
 var data=str.split(';');
 var obj={};
 for(var i=0;i<data.length;i++){
 var propArray=data[i].split(':');
 obj[propArray[0]]=propArray[1]
 }

Answer 5

There is no straight way. Just parse that string. For example:

var str = "username:joe_1987;password:123456;email:[email protected];"
var arr = str.split(';');
var o = {};
for (a in arr) {
 if (arr[a]) {
 o[arr[a].split(':')[0]]=arr[a].split(':')[1];
 }
}
console.log(o);
