Question

/search.aspx?Search=test

function getQuery(name) {
    var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
};


if (getQuery('SearchType') == '') {
   $("#txtSearch").val(getQuery('Search'));
};

if I leave out the if statement and just set the value of the textbox it works fine, so I obviously know my getQuery function is working. It’s obviously something to do with the fact that SearchType is NOT ”, it’s not anything. I tried “if (getQuery(‘SearchType’)) but that didn’t work either.

Must be a simple answer… there always is to my questions 🙂

Answer 1

It’s because you’re comparing to an empty string, but getQuery is returning null. Change your comparison to this:

if (getQuery('SearchType') == null) {
   $("#txtSearch").val(getQuery('Search'));
};
