Question

I have an object which I want to filter. This is what I use:

query = {
   "teststring-123": "true",
   "teststring-12344566": "false",
   test: "true"
}

I want to filter query so that after filtering I just have:

query = {
   "teststring-123": "true",
   "teststring-12344566": "false"
}

$(query).each(function(index, value) {
    $.each(value, function(i, v) {
        if(i.indexOf('teststring-')==-1) {
            // remove part of query object where index is this one       
            console.log(index)
        }
    });     
});

How can I handle this?

Use the delete operator:

$.each(query, function(key, value) {
    if(key.indexOf('teststring-') == -1) {
        delete query[key];
    }
});
