How to grab substring before a specified character jQuery or JavaScript

Question

I am trying to extract everything before the ',' comma. How do I do this in JavaScript or jQuery? I tried this and not working..

1345 albany street, Bellevue WA 42344

I just want to grab the street address.

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

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.

Solution 5

If you like it short simply use a RegExp:

var streetAddress = /[^,]*/.exec(addy)[0];
