那些琐碎的知识-----搜索回车跳转页面

如图搜索框，想要实现文本输入内容后敲击回车（等同于点击后面的小放大镜图标）后跳转到搜索结果的页面

<div class="head-ss02">

       <input name="ss" type="text" id="search" onkeypress="javascript:enterSubmitss(this,event);" size="2" />

       <input type="text" id="sname" style="display: none" />

</div>

<div class="head-ss01">

      <a href="javascript:OnSubmit('search')">
　　　　　　<img src="images/ss.png" border="0" />
　　　 </a>

</div>

js代码如下：

<script type="text/javascript">

        function OnSubmit(tags) {

            var tag = document.getElementById(tags);

            if (tag.value == "") {

                window.location.href = "Searchkeyword.aspx?key=" + tag.value;

            }

            if (tag.length > 20) {

                alert("您输入的字符太长，小于20个字符");

                return false;

            }

            window.location.href = "Searchkeyword.aspx?key=" + tag.value;

        }

        function enterSubmitss(src, e) {

            if (window.event)

                keyPressed = window.event.keyCode; // IE

            else

                keyPressed = e.which; // Firefox

            if (keyPressed == 13) {

                submitFormss();



            }

        }

        function submitFormss() {

            var tag = document.getElementById("search");

           

            if (tag.value == "") {

                window.location.href = "Searchkeyword.aspx?key=" + tag.value;

            }

            if (tag.length > 20) {

                alert("您输入的字符太长，小于20个字符");

                return false;

            }

          

            location.href = "Searchkeyword.aspx?key=" + tag.value;

            

        }

</script>
