Question

我有以下代码来获取查询字符串值并返回不同的链接，具体取决于用户选择的过滤器（使用查询字符串重新加载页面）。

如果用户选择过滤器并重新加载页面，则可以正常工作。但是，第一次加载页面时没有查询字符串，javascript会导致某些图像/链接无法显示。代码

var goPage=new Array(6);

var search = location.search;
search = search.replace(/\?/,'');
var searchAttributes = search.split('&');

for(var no=0;no<searchAttributes.length;no++){
    var items = searchAttributes[no].split('=');
    eval("var "+items[0]+" = '"+items[1]+"';");
}
queryString = SelectedID;

var goPage=new Array(6);

if (queryString == "")
{
goPage[0]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Objective%20Status.aspx';
goPage[1]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Priorities%20Status.aspx';
goPage[2]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Milestone%20Status.aspx';
goPage[3]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Moved%20to%20Green%20Last%2030.aspx';
goPage[4]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Moved%20to%20Amber%20Last%2030.aspx';
goPage[5]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Moved%20to%20Red%20Last%2030.aspx';
}

if (queryString == 25)
{
goPage[0]='https://company.sharepoint.apac.microsoftonline.com/Lists/Strategic%20Items/Objective%20Status.aspx?View={D2ADE53F-8C47-4787-80AE-6F90C84206B5}&FilterField1=Strategic_x0020_ObjectiveFilterValue1=A.%20Industry%20leadership%20through%20technical%20excellence%2C%20self%20performance%2C%20safety%20and%20environment';

有关如何更改查询字符串的方式的任何建议，如果没有javascript也不会中断？

你可以使用这样的东西：

GetQueryStringValue:function(url, name) 
{       
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( url );
    if( results == null )
        return undefined;       
    return results[1];      
};

然后你可以这样做：

var SelectedID = GetQueryStringValue(window.location.href, 'SelectedID');
if(SelectedID)
{
   if(SelectedID==25)
   {
       //goPage[...]
   }
}
else
{
    //SelectedID is undefined
    //goPage[...]
}

如何使用javascript获取查询字符串，如果没有查询字符串
