The easiest and most idiomatic way to do this in JavaScript is using the URL
class: 在JavaScript中最简单,最惯用的方式是使用
URL
类:
const url = new URL('https://www.yellowpages.com/search?search_terms=Generator+Repair&geo_location_terms=Adamsville%2C+Alabama') console.log(url.searchParams.get('search_terms')); console.log(url.searchParams.get('geo_location_terms'));
You can use the following Javascript code to store the GET parameters into an object: 您可以使用以下Javascript代码将GET参数存储到对象中:
<script>
var URL = "https://www.yellowpages.com/search?search_terms=Generator+Repair&geo_location_terms=Adamsville%2C+Alabama";
var result = {};
URL.substring(URL.indexOf("?") + 1).split('&').forEach(function(x){
var arr = x.split('=');
arr[1] && (result[arr[0]] = arr[1]);
});
console.log(result.search_terms);
//OUTPUT: "Generator+Repair"
console.log(result.geo_location_terms);
//OUTPUT: "Adamsville%2C+Alabama"
</script>
You can use the following regex to get the 2 values: 您可以使用以下正则表达式获取2个值:
/search_terms=(.*)&geo_location_terms=(.*)/
This is a very basic regex, that starts by matching ' search_terms=
' then creates a Group
that matches any number of any char
up to the '&'
sign, then matches ' geo_location_terms='
and finally creates a Group that matches any number of any char
. 这是一个非常基本的正则表达式,首先匹配“
search_terms=
”,然后创建一个匹配任何数量的any char
的Group
,直到'&'
号,然后匹配“ geo_location_terms='
,最后创建一个匹配任何数量的Group的正则表达式。 any char
。
Your desired output will be in Group 1
and Group 2
. 您所需的输出将在
Group 1
Group 2
和Group 2
。
How to use: 如何使用:
var url = 'https://www.yellowpages.com/search?search_terms=Generator+Repair&geo_location_terms=Adamsville%2C+Alabama';
var regex = /search_terms=(.*)&geo_location_terms=(.*)/;
var match = url.match(regex);
var search_terms = match[1];
var geo_location_terms = match[2];
