ViewsHow to delete multiple url params
There is a problem with deleting several string parameters. Only the last parameter is being deleted now.
upd: I did not specify that I wanted to achieve the ability to remove specific parameter values
this code does not work correctly:
const updateFiltersSearchParams = (paramKey, newValue) => {
const isParamExist = searchParams.getAll(paramKey).includes(newValue);
if (!isParamExist) {
searchParams.append(paramKey, newValue);
setSearchParams(searchParams);
} else {
const updatedSearchParams = new URLSearchParams(
[...searchParams].filter(
([key, value]) => key !== paramKey || value !== newValue
)
);
setSearchParams(updatedSearchParams);
}
};
const handleDeleteParams = () => {
[...checkboxParams].forEach((param) => {
updateFiltersSearchParams("selected", param);
});
};

change your handleDeleteParams function with this
const handleDeleteParams = () => {
setSearchParams([]);
};

If you want to delete *only the selected (or any specific queryString key) queryString parameters you can use the delete method of the URLSearchParams object, then enqueue the params URL update.
const handleDeleteParams = (key) => {
searchParams.delete(key);
setSearchParams(searchParams);
};
...
<button type="button" onClick={() => handleDeleteParams("selected")}>
Clear all "selected" params
</button>

Solved the problem by modifying the function like this
const toggleSearchParams = (params) => {
const newSearchParams = [...searchParams];
for (const prevParam of params) {
const index = newSearchParams.findIndex(
(newParam) =>
prevParam[0] === newParam[0] && prevParam[1] === newParam[1]
);
if (index === -1) {
newSearchParams.push(prevParam);
} else {
newSearchParams.splice(index, 1);
}
}
setSearchParams(new URLSearchParams(newSearchParams));
};
const handleChangeCheckBoxValue = (e) => {
toggleSearchParams([["selected", e.target.value]]);
};
const handleDeleteParams = () => {
toggleSearchParams(checkboxParams.map((param) => ["selected", param]));
};
