from中嵌套from的一种方法

html前台代码为：

div class="mainsearch clearfix">
                        <form method="post" name="CatalogSearchForm" action='proList.aspx'
                        id="CatalogSearchForm">
                        <div class="searcharea">
                            <input type="text" onfocus="$('#searchKeywords')[0].value=''; document.getElementById('searchKeywords').onfocus = Function('void(0)');"
                                name="searchKeywords" id="searchKeywords" value="D7000" />
                        </div>
                        <div class="searchnow">
                            <a title="搜索" href="" onclick="searchProduct();">搜索</a></div>
                            <script type="text/javascript">
                        function searchProduct()
                        {
                           var name=$("#searchKeywords").val();
                           window.open("proList.aspx?ProName="+name);
                        }
                    </script>
                    </form>
                    </div>
