go to link on button click - jquery
提问by blasteralfred Ψ
I have a script as below
我有一个脚本如下
$('.button1').click(function() {
document.location.href=$(this).attr('id');
});
the button1 has variable unique ids. on click, the page must redirect to url "www.example.com/index.php?id=buttonid" but now the page is redirecting only to "button id".
button1 具有可变的唯一 ID。单击时，页面必须重定向到 url“ www.example.com/index.php?id=buttonid”，但现在页面仅重定向到“ button id”。
I want to add the string "www.example.com/index.php?id=" before the current url. How can I make this possible?
我想www.example.com/index.php?id=在当前 url 之前添加字符串“ ”。我怎样才能做到这一点？

$('.button1').click(function() {
window.location = "www.example.com/index.php?id=" + this.id;
});
First of all using window.locationis better as according to specification document.locationvalue was read-only and might cause you headaches in older/different browsers. Check notes @MDC DOM document.location page
首先，使用window.location更好，因为根据规范document.location值是只读的，可能会导致您在旧版/不同浏览器中头疼。检查注释@ MDC DOM document.location 页面
And for the second - using attrjQuery method to get id is a bad practice - you should use direct native DOM accessor this.idas the value assigned to thisis normal DOM element.
对于第二个 - 使用attrjQuery 方法获取 id 是一种不好的做法 - 您应该使用直接本机 DOM 访问器，this.id因为分配给的值this是普通 DOM 元素。

You need to specify the domain:
您需要指定域：
$('.button1').click(function() {
window.location = 'www.example.com/index.php?id=' + this.id;
});

$('.button1').click(function() {
document.location.href='/index.php?id=' + $(this).attr('id');
});

Why not just change the second line to
为什么不把第二行改为
document.location.href="www.example.com/index.php?id=" + $(this).attr('id');

you can get the current url with window.location.hrefbut I think you will need the jQuery query plugin to manipulate the query string: http://plugins.jquery.com/project/query-object
您可以获得当前的 url，window.location.href但我认为您将需要 jQuery 查询插件来操作查询字符串：http: //plugins.jquery.com/project/query-object
