I am trying to add value of each checkbox to URL searchParams, first time when I check a checkbox it works good, but when I reload page, it not work anymore, what I have done wrong? I mean it works when it is state but after page load, not working, how can I fix this?
function setURL(query){
//var url = window.location.protocol + "//" + window.location.host + window.location.pathname;
var url = window.location.href;
let newURL = new URL(url);
newURL.searchParams.append('brands', query)
window.history.replaceState(null, null, newURL);
}
function checkURL(){
var url = window.location.href;
let newURL = new URL(url);
window.history.replaceState(null, null, newURL);
if(newURL.searchParams.has('brands')){
let currentBrands = newURL.searchParams.get('brands');
let brandsArray = currentBrands.split(',');
brandsArray.map(function(v,i){
jQuery('input[name="pa_brand"][value="'+v+'"]').click();
});
}
}
checkURL();
let array = [];
jQuery('input[name="pa_brand"]').change(function(){
let value = this.value;
let id = array.indexOf(value);
if(jQuery(this).is(':checked')){
array.push(value)
} else {
array.splice(id, 1);
}
setURL(array.toString())
console.log(array)
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="pa_brand" value="116"/>
<input type="checkbox" name="pa_brand" value="117"/>
<input type="checkbox" name="pa_brand" value="118"/>First of all replace newURL.searchParams.append('brands', query) with newURL.searchParams.set('brands', query). It will solve your problem also in the checkURL put initial value to array variable. I edited your code after these two changes and everythin seems ok.
let array = [];
function setURL(query){
//var url = window.location.protocol + "//" + window.location.host + window.location.pathname;
var url = window.location.href;
let newURL = new URL(url);
newURL.searchParams.set('brands', query)
window.history.replaceState(null, null, newURL);
}
function checkURL(){
var url = window.location.href;
let newURL = new URL(url);
window.history.replaceState(null, null, newURL);
if(newURL.searchParams.has('brands')){
let currentBrands = newURL.searchParams.get('brands');
let brandsArray = currentBrands.split(',');
array = brandsArray;
brandsArray.map(function(v,i){
jQuery('input[name="pa_brand"][value="'+v+'"]').click();
});
}
}
checkURL();
jQuery('input[name="pa_brand"]').change(function(){
let value = this.value;
let id = array.indexOf(value);
if(jQuery(this).is(':checked')){
array.push(value)
} else {
array.splice(id, 1);
}
setURL(array.toString())
console.log(array)
})
