    Enter key press execute button click

    Hi there

    I have the code bellow on a page where I want when a user hits enter it execute the code of button click, but when I press enter it behave like a submit button. If I remove the tags "<form> & </form>" it does work on ie only.
    Does anyone can help me please?

    <html>
    <script>
    function createRequestObject() {
    var ro;
    var browser = navigator.appName;
    if(browser == "Microsoft Internet Explorer"){
    ro = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
    ro = new XMLHttpRequest();
    }
    return ro;
    }

    var http = createRequestObject();

    function stteam1(str1) {
    http.open('get', 'test2.asp?id='+escape(str1)+'&'+Math.random()*Math.random());
    http.onreadystatechange = handlestteam1;
    http.send(null);
    }

    function handlestteam1() {
    if(http.readyState == 4){
    var response = http.responseText;
    var update = new Array();

    if(response.indexOf('|' != -1)) {
    update = response.split('|');
    document.getElementById("posi1").innerHTML = update[0];
    }
    }
    }
    </script>
    <body>
    <form>
    <input type="text" name="n" autocomplete="off" onkeypress="if (event.keyCode == 13) stteam1(n.value);" />
    <input type="button" value="Search" onClick="stteam1(n.value);">
    </form>
    <div id="posi1"></div>
    </body>
    </html>

    Thanks

    Hmm, I can't see what is wrong with the code. Have you tried Stackoverflow? Or here. There is a thread dealing with a similar isse, probably, it will help.

    In your line
    Code:
    if(response.indexOf('|' != -1)) {
    it seems your first close parenthesis should be after '|' . You are looking at indexOf for one character only which the outer parenthesis should be able test now.

    Just a few thoughts...

    In your keypress event, have you tried using event.preventDefault() to prevent the form submission?

    You don't need to do that, you only need action="javascript:;" in the <form> tag to prevent any form action submitting the form.
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
