How to get a multiple value from a text box?


I have created web application and textbox as a textarea. I am using javascript for validation. When I enter value in text box so it should be number not alphabet I have use textmode is multiple line.

My problem is that how I get multiple value from textbox and store in array in javascript and check each value is number or not. I am using the web form. Please help me.

You can get the value from a textarea like

var txtvalue = document.getElementById("txtareaid").value

and if are using a separator then something like

var txtvaluearray = document.getElementById("txtareaid").value.split(';')

will get you all the values in an array if the seperator is ;


As per your update you can use \n as the separator and as pointed by @Sohnee you can do the validation.
