VB.NET：在文本框中按Enter时如何执行jquery代码

Question

I have an issue where I'm trying to execute a search query from a textbox and attempting to use enter to initiate the search; however, it doesn't seem to be working. I'm wondering if vb.net/asp.net is doing a postback or something that I'm not aware of.

ASPX Page

 <form class="navbar-search">
     <input id="searchbox" type="text" class="search-query span3" placeholder="Search" />
     <div class="icon-search"></div>
 </form>

JQuery

$('#searchbox').keyup(function (e) {
    //alert("this will execute");
    if (e.which == 13) {
        alert("this will not execute");
        //window.location.href = "http://www.google.com/";
    }
});

I can't get the alert box to execute or the change location to work... if anyone can help I appreciate it.

Answer 1

Try this:

$("#searchbox").keypress(function (e) {
    //alert("this will execute");
    var code = e.keyCode || e.which;
    if (code == 13) {
        alert("this will not execute");
        //window.location.href = "http://www.google.com/";
    }
});

and to stop page from refreshing on-enter use this:

$(document).keydown(function (e) {
    var code = e.keyCode || e.which;
    if (code === 13) {
        e.preventDefault();
    }
});

FIDDLE

Please try this.

$("#searchbox").live("keyup", function(event) {
        if (event.keyCode == 13) {
            //window.location.href = "http://www.google.com/";
        }
    });

This was worked for me...
