How can I bind to the change event of a textarea in jQuery?
Try this actually:
$('#textareaID').bind('input propertychange', function() { $("#yourBtnID").hide(); if(this.value.length){ $("#yourBtnID").show(); }});DEMO
That works for any changes you make, typing, cutting, pasting.
bind is deprecated. Use on:
$("#textarea").on('change keyup paste', function() { // your code here});Note: The code above will fire multiple times, once for each matching trigger-type. To handle that, do something like this:
var oldVal = "";$("#textarea").on("change keyup paste", function() { var currentVal = $(this).val(); if(currentVal == oldVal) { return; //check to prevent multiple simultaneous triggers } oldVal = currentVal; //action to be performed on textarea changed alert("changed!");});
Use an input event.
var button = $("#buttonId");$("#textareaID").on('input',function(e){ if(e.target.value === ''){ // Textarea has no value button.hide(); } else { // Textarea has a value button.show(); }});
