How to read line by line of a text area HTML tag
Try this.
var lines = $('textarea').val().split('\n');for(var i = 0;i < lines.length;i++){ //code here using lines[i] which will give you each line}
This works without needing jQuery:
var textArea = document.getElementById("my-text-area");var arrayOfLines = textArea.value.split("\n"); // arrayOfLines is array where every element is string of one line
This would give you all valid numeric values in lines
. You can change the loop to validate, strip out invalid characters, etc - whichever you want.
var lines = [];$('#my_textarea_selector').val().split("\n").each(function (){ if (parseInt($(this) != 'NaN') lines[] = parseInt($(this));}
