In my HTML page, I had a textbox for user to input keyword for searching. When they click the search button, the JavaScript function will generate a URL and run in new window.
The JavaScript function work properly when the user clicks the search button by mouse, but there is no response when the user presses the ENTER key.
function searching(){
var keywordsStr = document.getElementById('keywords').value;
var cmd ="http://XXX/advancedsearch_result.asp?language=ENG&+"+ encodeURI(keywordsStr) + "&x=11&y=4";
window.location = cmd;
}
<form name="form1" method="get">
<input name="keywords" type="text" id="keywords" size="50" >
<input type="submit" name="btn_search" id="btn_search" value="Search"
onClick="javascript:searching(); return false;" onKeyPress="javascript:searching(); return false;">
<input type="reset" name="btn_reset" id="btn_reset" value="Reset">
</form>
As scoota269 says, you should use onSubmit
instead, cause pressing enter on a textbox will most likey trigger a form submit (if inside a form)
<form action="#" onsubmit="handle">
<input type="text" name="txt" />
</form>
<script>
function handle(e){
e.preventDefault(); // Otherwise the form will be submitted
alert("FORM WAS SUBMITTED");
}
</script>
If you want to have an event on the input-field then you need to make sure your handle()
will return false, otherwise the form will get submitted.
<form action="#">
<input type="text" name="txt" onkeypress="handle(event)" />
</form>
<script>
function handle(e){
if(e.keyCode === 13){
e.preventDefault(); // Ensure it is only this code that runs
alert("Enter was pressed was presses");
}
}
</script>
