一、取参
function getAllUrlParams(url) {
var queryString = url ? url.split('?')[1] : window.location.search.slice(1);
var obj = {};
if (queryString) {
queryString = queryString.split('#')[0];
var arr = queryString.split('&');
for (var i = 0; i < arr.length; i++) {
var a = arr[i].split('=');
var paramNum = undefined;
var paramName = a[0].replace(/[d*]/, function (v) {
paramNum = v.slice(1, -1);
return '';
});
// 设置参数值（如果为空则设置为true）
var paramValue = typeof (a[1]) === 'undefined' ? true : a[1];
// paramName = paramName.toLowerCase();
// paramValue = paramValue.toLowerCase();
if (obj[paramName]) {
if (typeof obj[paramName] === 'string') {
obj[paramName] = [obj[paramName]];
}
if (typeof paramNum === 'undefined') {
obj[paramName].push(paramValue);
} else {
obj[paramName][paramNum] = paramValue;
}
} else {
obj[paramName] = paramValue;
}
}
}
return obj;
}
console.log(getAllUrlParams('http://display.intdmp.com/site_login_ijf.htm?app_key=adhu3e534be06456426b&acc=asda'));
//{app_key: "adhu3e534be06456426b", acc: "asda"}
二、存参
pasting
function toQueryPair(key, value, bo) {
if (typeof value === 'undefined') {
return key;
}
return key + '=' + (bo ? encodeURIComponent(value === null ? '' : String(value)) : value === null ? '' : String(
value));
}
const toBodyString = function (obj, bo = true) {
let ret = [];
for (let key in obj) {
let values = obj[key];
if (values && values.constructor === Array) { //数组
let queryValues = [];
for (let i = 0, len = values.length, value; i < len; i++) {
value = values[i];
queryValues.push(toQueryPair(key, value));
}
ret = ret.concat(queryValues);
} else { //字符串
ret.push(toQueryPair(key, values, bo));
}
}
return ret.join('&');
}
console.log(toBodyString({
a: 123546,
b: 'fdfdfd',
c: '9999'
})); //a=123546&b=fdfdfd&c=9999
