I have create a HTML page with some JavaScript code. Here is the code
<script type="text/javascript">
function doIt(){
window.location = document.getElementById('url').value;
}
</script>
<input type="text" id="url" />
I want that when some one press the enter after type the URL. The page redirect to the given URL automatically. How i can do this? Please suggest me some code
Use below code:
<html>
<html>
<head>
<script type="text/javascript">
function doIt(){
window.location.href = document.getElementById('url').value;
}
document.onkeypress=function(e){
var e=window.event || e;
if(e.keyCode===13) doIt();
}
</script>
</head>
<body>
<input type="text" id="url" value="http://www."/>
</body>
</html>
keypress to the document element. That is not the ideal solution...
see live demo at http://jsfiddle.net/qiao/RGqwD/2/
var input = document.getElementById('url');
input.onkeydown = function(e) {
var key = e.keyCode || e.which;
if (key == 13) {
window.location = input.value;
}
};
Here is solution: http://jsfiddle.net/YBLQx/1/
JS
(function () {
var textField = document.getElementById('foo');
function addHandler(el, event, handler) {
if (el.addEventListener) {
el.addEventListener (event, handler, false);
} else if (el.attachEvent) {
el.attachEvent (event, handler);
}
}
addHandler(textField, 'keydown', textEntered);
function textEntered(event) {
if (event.keyCode === 13) {
window.location = textField.value;
}
}
}());
HTML
<input type="text" id="foo" />
Best regards!
<input type="text" id="url" onblur="window.location.href='this.value'" />
the above is if the focus is taken out, like pressing tab
and then for enter, write onkeydown handler
<script type="text/javascript">
document.getElementById('url').onkeydown = function(e) {
var keyCode = e.keyCode || e.which;
if (keyCode === 13) {
window.location.href = this.value;
}
}
</script>
If your not using jQuery, the following is a complete example:
function addEvent(obj, type, fn) {
if (obj.attachEvent) {
obj['e' + type + fn] = fn;
obj[type + fn] = function() {
obj['e' + type + fn](window.event);
}
obj.attachEvent('on' + type, obj[type + fn]);
} else obj.addEventListener(type, fn, false);
}
addEvent(window, 'load', function() {
addEvent(document.getElementById('url'), 'keyup', function(e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 13)
window.location.href = this.value;
});
});

You need to attach a keypress event handler to the text box. In your event handler, you would check if the key pressed was enter. If so, do the redirect. Look up event handlers.
