I have a text area where each line contains Integer value like follows
1234
4321
123445
I want to check if the user has really enetered valid values and not some funny values like follows
1234,
987l;
For that I need to read line by line of text area and validate that. How can i read line by line of a text area using javascript?
Try this.
var lines = $('textarea').val().split('\n');
for(var i = 0;i < lines.length;i++){
//code here using lines[i] which will give you each line
}
