问题描述

大家好，

我是JQuery的初学者，我想将一个textbox 值分配给另一个textbox.我已经为此编写了代码:

Hi all of you,

I''m a beginner in JQuery and I want to assign one textbox value to another textbox. I have written a code for that like:

<script type="text/javascript">
    $("#btnTest").click(function(event) {
        event.preventDefault();
        $("#txtLastName").val() = $("input:txtFirstName").val();
    });
</script>

但它不起作用.
有人可以帮我吗?

("#btnTest").click(function(event) { event.preventDefault();

(#txtLastName").val()=

("#txtLastName").val() =

("input:txtFirstName").val() ; }); < /script >
