How to grab substring before a specified character jQuery or JavaScript

Solution 1:

var streetaddress= addy.substr(0, addy.indexOf(',')); 

While it's not the best place for definitive information on what each method does (mozilla developer network is better for that) w3schools.com is good for introducing you to syntax.

Solution 2:

var streetaddress = addy.split(',')[0];

Solution 3:

try this:

streetaddress.substring(0, streetaddress.indexOf(','));

Solution 4:

//split string into an array and grab the first item

var streetaddress = addy.split(',')[0];

Also, I'd recommend naming your variables with camel-case(streetAddress) for better readability.
