javascript - 在选择电台，重定向到一个链接

Question

我有三个收音机，我希望将任何人的 onselect 重定向到一个链接。使用 javascript 或 jquery

    All <input name="EventRadio" type="radio" value="" checked="checked"/>&nbsp;
    Events<input name="EventRadio" type="radio" value="Events" />&nbsp;Classes<input name="EventRadio" type="radio" value="Classes"/><br /><br />

因此，由于默认选中“全部”，我希望它转到 mysite.com/search.aspx。现在，如果用户选择事件，我想将用户重定向到 mysite.com/search?type=Events 或者如果用户选择类，我想将用户重定向到 mysite.com/search?type=Classes 作为对 onselect 的响应收音机。我如何实现这一目标？

Answer 1

All     <input name="EventRadio" type="radio" value="" checked="checked" onclick ="goToLocation(this.value)"/>&nbsp;
Events  <input name="EventRadio" type="radio" value="Events" onclick ="goToLocation(this.value)"/>&nbsp;
Classes <input name="EventRadio" type="radio" value="Classes" onclick ="goToLocation(this.value)"/><br /><br />


function goToLocation(val){
 if(val == "Events")
     window.location = "go to Events location";
 if(val == "Classes")
     window.location = "go to Classes location";
window.location = "go to default location";

}

作为演示：

var inputs = document.getElementsByTagName('input'),
    radios = [],
    output = document.getElementById('output'),
    url = 'mysite.com/search?type=';

for (var i = 0, len = inputs.length; i<len; i++) {
    if (inputs[i].type == 'radio'){
        radios.push(inputs[i]);
    }
}

for (var r=0, leng = radios.length; r<leng; r++){
    radios[r].onchange = function(){
        if (this.value){
            /* in real life use:
            document.location = url + this.value;
            */
            output.innerHTML = url + this.value;
        }
        else {
            /* in real life use:
            document.location = 'mysite.com/search?type=Events';
            */
            output.innerHTML = 'mysite.com/search.aspx';
        }
    }
}

请注意，我还更改了您的标记以使用<label>元素，并删除了 s 和<br />s。

$('input').click(function(){
    var val = $(this).val();
    if(val !== ''){
        window.location = 'http://mysite.com/search?type=' + val;
    }else{
        window.location = 'http://mysite.com/search.aspx';
    }
});
