更改使用jQuery的DropDownList从一个页面 [英] Changing a page from DropDownList using jQuery

问题描述

我有一个简单的jQuery脚本，从静态的dropdownlist选择当前页面，当选择更改脚本还修改一个锚标记的href属性，以反映导航的变化。这里是我的code：

I have a simple jQuery script that selects the current page from a static dropdownlist, and when the selection changes the script also modifies the href attribute of an anchor tag to reflect the navigation change. Here is my code:

<select name="PageSelectDropDown" id="PageSelectDropDown"> 
    <option value="Insulation">Insulation</option> 
    <option value="Windows">Windows</option> 
    <option value="Siding">Siding</option> 
    <option value="Roofing">Roofing</option> 
    <option value="Gutters">Gutters &amp; Gutter Protection</option> 
    <option value="PatioDoors">Patio Doors</option>
</select> 
<a href="" id="clicker">Go!</a> 

<script type="text/javascript">
$(document).ready(function () {
    //get the current page
    var cPage = '<%= ViewData["CurrentPage"] %>';

    //select the current page from the list
    $("#PageSelectDropDown > option").each(function () {
        if ($(this).val().toLowerCase() == cPage.toLowerCase()) {
            $(this).attr("selected", "selected");
        }
    });

    //change the link target
    $("#PageSelectDropDown").change(function () {
        var str = "";
        $("#PageSelectDropDown option:selected").each(function () {
            str += $(this).val() + " ";
        });
        $("#clicker").attr("href", "/Product/" + str.trim());
        if (cPage != str.trim()) {
            $("#clicker").click();
        }
    });
});
</script>

我想看到这个唯一的改进是将自动更改（自动点击锚标记），当用户从DropDownList中选择一个不同的页面。

The only improvement I would like to see on this is for page to automatically change ('auto-click' anchor tag) when the user selects a different page from the dropdownlist.

在此先感谢！

推荐答案

如果我正确地理解你的问题，你问你怎么自动重定向，而不​​必点击需要给定的URL，？

If I understand your question correctly, you are asking how do you automatically redirect to the given url, instead of having a click needed?

用JavaScript，你可以简单地使用 window.location的属性来重定向浏览器。

With Javascript, you can simply use the window.location property to redirect the browser.

window.location = '/somepath/someurl.htm';

这将绕过任何需要点击一个按钮，就等设置的位置的任何值在下拉菜单中选择。

This will bypass any need for a button click, etc. Just set the location to whatever value is selected in the dropdown.
