使用 jQuery 获取 URL 参数并将它们显示在 HTML 输入文本字段中 [英] Get URL parameters with jQuery and display them inside an HTML input text field

问题描述

我在这里和谷歌上浏览了数十篇关于此的文章，但似乎没有一篇有用.我正在尝试从 URL 获取参数并将它们显示在输入文本字段中.

I been through dozens of articles on this on here and on Google but none of them seemed to have worked. I am trying to get parameters from the URL and display them inside an input text field.

这是我正在处理的代码:

This is the code I'm working on:

function getQueryVariable(variable)
{
   var query = window.location.search.substring(1);
   var vars = query.split("&");
   for (var i=0;i<vars.length;i++) {
           var pair = vars[i].split("=");
           if(pair[0] == variable){return pair[1];}
   }
   return(false);
}

getQueryVariable("inputline1");
getQueryVariable("inputline2");

<input type="text" id="inputline1" value="getQueryVariable('inputline1')" />
<input type="text" id="inputline2" value="getQueryVariable('inputline2')" />

我正在尝试的网址:

?inputline1=sampletext1&inputline2=sampletext2

我的 jQuery 知识非常有限，任何有关正确方向的帮助都会非常有帮助.

My jQuery knowledge is very limited and any help on the right direction on this would be very helpful.

提前致谢.

推荐答案

终于可以工作了，更新了下面的工作脚本以帮助将来的任何人:

Got it finally to work, updated a working script below to help anyone in the future:

function getQueryVariable(variable) {
                var query = window.location.search.substring(1);
                var parms = query.split('&');
                for (var i = 0; i < parms.length; i++) {
                    var pos = parms[i].indexOf('=');
                    if (pos > 0 && variable == parms[i].substring(0, pos)) {
                        return parms[i].substring(pos + 1);;
                    }
                }
                return "";
}

getQueryVariable("inputline1");

$(function () {
        $('#inputline1').val(getQueryVariable('inputline1'))
});

<input type="text" id="inputline1" />

带参数的网址:

?inputline1=Sample
