See the project through the JS array split method format query string, the whim why not use the regular then, how performance? So we have the following code:
Copy Code code as follows:
var url= ' www.baidu.com?a=123&b=456&c=789&e=dfsdfsdfsdfsdfsdfsdf&f=46545454545454785&g= E23232DSFVDFVDF ';
/**
* Format query string (Regular implementation)
* @param URL URL address
* @return JSON object formatted with {object}
*/
function FormatUrl (URL) {
var reg=/(?: [? &]+) ([^&]+) = ([^&]+)/g;
var data={};
function fn (str,pro,value) {
Data[decodeuricomponent (PRO)]=decodeuricomponent (value);
}
Url.replace (REG,FN);
return data;
}
/**
* Format query string (array implementation)
* @param URL URL address
* @return JSON object formatted with {object}
*/
function FormatUrl2 (URL) {
Url=url.replace (/.*\?/, "");
var args={},
Items=url.length?url.split ("&"): []
, Item=null
, i=0
, Len=items.length;
for (i=0;i<items.length;i++) {
Item=items[i].split ("=");
Args[decodeuricomponent (Item[0])]=decodeuricomponent (item[1]);
}
return args;
}
var starttime=new Date ();
for (Var i=0;i<1000000;i++) {
FORMATURL2 (URL);
}
Console.log (' FormatUrl2 ', (New Date ()-starttime)); FormatUrl2 12138
Starttime=new Date ();
for (Var i=0;i<1000000;i++) {
FormatUrl (URL);
}
Console.log (' FormatUrl ', (New Date ()-starttime)); FormatUrl 12537
The test browser is chrme 25; the function of the regular implementation is slower than the function of the array implementation (tears running ...). ）。 But luckily, it's only 0.4 seconds to repeat 1 million times.
