我有一个带有一些GET参数的URL,如下所示:

www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5 

我需要得到c的全部值。我试图读取URL,但只得到m2。如何使用JavaScript执行此操作?

您可以添加一个输入框,然后要求用户将值复制到其中……这非常简单:

<h1>Hey User! Can you please copy the value out of the location bar where it says like, &m=2? Thanks! And then, if you could...paste it in the box below and click the Done button?</h1>
<input type='text' id='the-url-value' />
<input type='button' value='This is the Done button. Click here after you do all that other stuff I wrote.' />

<script>
//...read the value on click

好吧,但说真的。。。我发现了这段代码,它似乎很有用:

function queryToJSON() {
    var pairs = location.search.slice(1).split('&');

    var result = {};
    pairs.forEach(function(pair) {
        pair = pair.split('=');
        result[pair[0]] = decodeURIComponent(pair[1] || '');
    });

    return JSON.parse(JSON.stringify(result));
}

var query = queryToJSON();

其他回答

function parseUrl(url){
    let urlParam = url.split("?")[1];
    console.log("---------> URL param : " + urlParam);
    urlParam = urlParam.split("&");
    let urlParamObject = {};
    for(let i=0;i < urlParam.length;i++){
        let tmp = urlParam[i].split("=");
        urlParamObject[tmp[0]] = tmp[1];
    }
    return urlParamObject;
}

let param = parseUrl(url);
param.a // output 10
param.b // output 20

我尝试了很多不同的方法,但当我在URL中查找参数值时,这个尝试过的真正的正则表达式函数对我很有用,希望这有帮助:

var text='www.test.com/t.html?a=1&b=3&c=m2-m3-m4-m5'函数QueryString(项,文本){var foundString=text.match(新RegExp(“[\?\&]”+item+“=([^\&]*)(\&?)”,“i”));返回foundString?foundString[1]:foundString;}console.log(QueryString('c',文本));

使用类似QueuryString('param_name',url),并将返回值

平方米-3米-4米

我需要读取一个URLGET变量,并根据URL参数完成一个操作。我到处寻找解决方案,结果发现了一小段代码。它基本上读取当前页面url,对url执行一些正则表达式,然后将url参数保存在关联数组中,我们可以轻松访问该数组。

作为一个例子,如果我们有下面的url,底部有javascript。

http://TestServer/Pages/NewsArchive.aspx?year=2013&Month=July

获取参数id和page所需要做的就是调用这个:

准则将是:

<script type="text/javascript">
var first = getUrlVars()["year"];
var second = getUrlVars()["Month"];

alert(first);
alert(second);
function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}
</script>

看看这个

function getURLParameters(paramName)
{
    var sURL = window.document.URL.toString();
    if (sURL.indexOf("?") > 0)
    {
        var arrParams = sURL.split("?");
        var arrURLParams = arrParams[1].split("&");
        var arrParamNames = new Array(arrURLParams.length);
        var arrParamValues = new Array(arrURLParams.length);

        var i = 0;
        for (i = 0; i<arrURLParams.length; i++)
        {
            var sParam =  arrURLParams[i].split("=");
            arrParamNames[i] = sParam[0];
            if (sParam[1] != "")
                arrParamValues[i] = unescape(sParam[1]);
            else
                arrParamValues[i] = "No Value";
        }

        for (i=0; i<arrURLParams.length; i++)
        {
            if (arrParamNames[i] == paramName)
            {
                //alert("Parameter:" + arrParamValues[i]);
                return arrParamValues[i];
            }
        }
        return "No Parameters Found";
    }
}
