js获取url中的查询参数

// 获取url中query
// return {cate_id: '1', street_id: '0'}
function getParams() {
	var url = location.search //获取url中"?"符后的字串
	var theRequest = new Object()
	if (url.indexOf("?") != -1) {
		var str = url.substr(1)
		strs = str.split("&")
		for (var i = 0; i < strs.length; i++) {
			theRequest[strs[i].split("=")[0]] = unescape(strs[i].split("=")[1])
		}
	}
	return theRequest
}

// 将json对象转成query字符串(不包含?)
// return cate_id=1&street_id=0
function parseParams(data) {
	try {
		var tempArr = []
		for (var i in data) {
			var key = encodeURIComponent(i)
			var value = encodeURIComponent(data[i])
			tempArr.push(key + '=' + value)
		}
		var urlParamsStr = tempArr.join('&')
		return urlParamsStr
	} catch (err) {
		return ''
	}
