Retrieve Multiple Key/values From Query String With Same Parameter

I'm trying to extract multiple parameters from a query string, where the parameter has the same name, in my case filter. I can only seem to access the first instance of the filter

Solution 1:

let parts = myURL.split("&");
let filters = {};
parts.forEach(part => {
  if (part.includes("filter")) {
    let value = part.split("=")[1];
    let key = value.split(":")[0];
    filters[key] = value.split(":")[1];
   }
})

Output:

{
  color: "'GOLD'",
  size: "'10'"
}

Solution 2:

No need to reinvent the wheel

There is already an excellent library for that: query-string

const query = require('query-string')

const url = 'someparam=test&filter=color:"GOLD"&filter=size:"10"';

const result = query.parse(url);
console.log(JSON.stringify(result));

output

{"filter":["color:\"GOLD\"","size:\"10\""],"someparam":"test"}

Solution 3:

    myURL =  `example.com?someparam=test&filter=color:"GOLD"&filter=size:"10"`;

var getUrlParameter = functiongetUrlParameter(sParam) {
    var sPageURL = myURL,
    sURLVariables = sPageURL.split('&'),
    sParameterName,
    i;

    return sURLVariables.filter(function(filters){
        return filters.includes(sParam);     
    }).map(function(filters){
        sParameterName = filters.split('=');
        if (sParameterName[0] !== undefined && sParameterName[0] === sParam && sParameterName[1] !== undefined) {
            returndecodeURIComponent(sParameterName[1]);
        }        
    })
}



var filters = getUrlParameter('filter');

console.log(filters);
