Focus Input Box On Load

Question

How can the cursor be focus on a specific input box on page load?

Is it posible to retain initial text value as well and place cursor at end of input?

<input type="text"  size="25" id="myinputbox" class="input-text" name="input2" value = "initial text" /> 

Answer 1

There are two parts to your question.

1) How to focus an input on page load?

You can just add the autofocus attribute to the input.

<input id="myinputbox" type="text" autofocus> 

However, this might not be supported in all browsers, so we can use javascript.

window.onload = function() {   var input = document.getElementById("myinputbox").focus(); } 

2) How to place cursor at the end of the input text?

Here's a non-jQuery solution with some borrowed code from another SO answer.

function placeCursorAtEnd() {   if (this.setSelectionRange) {     // Double the length because Opera is inconsistent about      // whether a carriage return is one character or two.     var len = this.value.length * 2;     this.setSelectionRange(len, len);   } else {     // This might work for browsers without setSelectionRange support.     this.value = this.value;   }    if (this.nodeName === "TEXTAREA") {     // This will scroll a textarea to the bottom if needed     this.scrollTop = 999999;   } };  window.onload = function() {   var input = document.getElementById("myinputbox");    if (obj.addEventListener) {     obj.addEventListener("focus", placeCursorAtEnd, false);   } else if (obj.attachEvent) {     obj.attachEvent('onfocus', placeCursorAtEnd);   }    input.focus(); } 

Here's an example of how I would accomplish this with jQuery.

<input type="text" autofocus>  <script> $(function() {   $("[autofocus]").on("focus", function() {     if (this.setSelectionRange) {       var len = this.value.length * 2;       this.setSelectionRange(len, len);     } else {       this.value = this.value;     }     this.scrollTop = 999999;   }).focus(); }); </script>
