Uri和javascript查询字符串操作。

这个项目结合了Steven Levithan的优秀parseUri正则表达式库。您可以安全地解析所有形状和大小的url，无论它们是多么无效或丑陋。

试一试 正则表达式，如此之慢，因此:

var SetParamUrl = function(_k, _v) {// replace and add new parameters

    let arrParams = window.location.search !== '' ? decodeURIComponent(window.location.search.substr(1)).split('&').map(_v => _v.split('=')) : Array();
    let index = arrParams.findIndex((_v) => _v[0] === _k); 
    index = index !== -1 ? index : arrParams.length;
    _v === null ? arrParams = arrParams.filter((_v, _i) => _i != index) : arrParams[index] = [_k, _v];
    let _search = encodeURIComponent(arrParams.map(_v => _v.join('=')).join('&'));

    let newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + (arrParams.length > 0 ? '?' +  _search : ''); 

    // window.location = newurl; //reload 

    if (history.pushState) { // without reload  
        window.history.pushState({path:newurl}, null, newurl);
    }

};

var GetParamUrl = function(_k) {// get parameter by key

    let sPageURL = decodeURIComponent(window.location.search.substr(1)),
        sURLVariables = sPageURL.split('&').map(_v => _v.split('='));
    let _result = sURLVariables.find(_v => _v[0] === _k);
    return _result[1];

};

例子:

        // https://some.com/some_path
        GetParamUrl('cat');//undefined
        SetParamUrl('cat', "strData");// https://some.com/some_path?cat=strData
        GetParamUrl('cat');//strData
        SetParamUrl('sotr', "strDataSort");// https://some.com/some_path?cat=strData&sotr=strDataSort
        GetParamUrl('sotr');//strDataSort
        SetParamUrl('cat', "strDataTwo");// https://some.com/some_path?cat=strDataTwo&sotr=strDataSort
        GetParamUrl('cat');//strDataTwo
        //remove param
        SetParamUrl('cat', null);// https://some.com/some_path?sotr=strDataSort

这就是我在服务器端(如Node.js)添加或更新一些基本url参数时使用的方法。

CoffeScript:

### @method addUrlParam Adds parameter to a given url. If the parameter already exists in the url is being replaced. @param {string} url @param {string} key Parameter's key @param {string} value Parameter's value @returns {string} new url containing the parameter ### addUrlParam = (url, key, value) -> newParam = key+"="+value result = url.replace(new RegExp('(&|\\?)' + key + '=[^\&|#]*'), '$1' + newParam) if result is url result = if url.indexOf('?') != -1 then url.split('?')[0] + '?' + newParam + '&' + url.split('?')[1] else if url.indexOf('#') != -1 then url.split('#')[0] + '?' + newParam + '#' + url.split('#')[1] else url + '?' + newParam return result

JavaScript:

function addUrlParam(url, key, value) { var newParam = key+"="+value; var result = url.replace(new RegExp("(&|\\?)"+key+"=[^\&|#]*"), '$1' + newParam); if (result === url) { result = (url.indexOf("?") != -1 ? url.split("?")[0]+"?"+newParam+"&"+url.split("?")[1] : (url.indexOf("#") != -1 ? url.split("#")[0]+"?"+newParam+"#"+ url.split("#")[1] : url+'?'+newParam)); } return result; } var url = "http://www.example.com?foo=bar&ciao=3&doom=5#hashme"; result1.innerHTML = addUrlParam(url, "ciao", "1"); <p id="result1"></p>

你可以使用URLSearchParams

const urlParams = new URLSearchParams(window.location.search);

urlParams.set('order', 'date');

window.location.search = urlParams;

.第一个农业是关键，第二个是价值。

注意:这在任何版本的ie浏览器中都不支持(但在Edge中支持)

我们可以导入node中的内置URL模块，如下所示

const { URL } = require('url');

例子:

Terminal $ node
> const { URL } = require('url');
undefined
> let url = new URL('', 'http://localhost:1989/v3/orders');
undefined
> url.href
'http://localhost:1989/v3/orders'
> let fetchAll=true, timePeriod = 30, b2b=false;
undefined
> url.href
'http://localhost:1989/v3/orders'
>  url.searchParams.append('fetchAll', fetchAll);
undefined
>  url.searchParams.append('timePeriod', timePeriod);
undefined
>  url.searchParams.append('b2b', b2b);
undefined
> url.href
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'
> url.toString()
'http://localhost:1989/v3/orders?fetchAll=true&timePeriod=30&b2b=false'

随着JS的新成就，这里是如何将查询参数添加到URL:

var protocol = window.location.protocol,
    host = '//' + window.location.host,
    path = window.location.pathname,
    query = window.location.search;

var newUrl = protocol + host + path + query + (query ? '&' : '?') + 'param=1';

window.history.pushState({path:newUrl}, '' , newUrl);

还有这种可能性Moziila URLSearchParams.append()
