我需要从网址字符串获取参数值
http://example.com/admin/param1/value1/param2/value2
我已经使用它做到了:
url.split('/param1/')[1].split('/')[0].replace(/\/$/, '');
但是还有其他更清洁的选择吗?像这样吗?
var url_string = "http://www.example.com/t.html?a=1&b=3&c=m2-m3-m4-m5"; //window.location.href
var url = new URL(url_string);
var c = url.searchParams.get("c");
console.log(c);
在这种情况下,
searchParams
不会给出期望的结果。请原谅如果已经有答案了。我找不到将其标记为重复之前,请仔细阅读该问题。
最佳答案
假设URL中始终带有/admin/
,则可以这样操作:
var testUrls = [
"http://example.com/admin/param1/value1/param2/value2",
"http://example.com/admin/name/John/age/50/paramWithNoVal",
];
for (var i = 0; i < testUrls.length; i++) {
var url = testUrls[i];
var paramArray = url.split("/admin/")[1].split("/");
var paramObj = {};
for (var x = 0; x < paramArray.length; x++) {
// i is even - assume this is a param name
if (x % 2 === 0) {
paramObj[paramArray[x]] = paramArray[x + 1] || null;
}
}
console.log(paramObj);
}
编辑:作为功能:
function getUrlParams(url) {
var paramArray = url.split("/admin/")[1].split("/");
var paramObj = {};
for (var x = 0; x < paramArray.length; x++) {
if (x % 2 === 0) {
paramObj[paramArray[x]] = paramArray[x + 1] || null;
}
}
return paramObj;
}
var url = "http://example.com/admin/param1/value1/param2/value2";
var params = getUrlParams(url);
console.log(params["param1"]);
console.log(params["param2"]);
