Hi,

I would like to know how to check an array in jquery to see if it contains a value?

var sitePrefList = { sitePrefs: [
				{ device: "mobile", value="1" },
				{ device: "desktop", value="2" }
			]
    };

Open in new window


I want to basically check if the user agent is mobile || desktop and then match it with the value in the array and display the value.

for (var i = 0; i < sitePrefList.sitePrefs.length; i++) {
            var sitePrefArray = new Array();
            sitePrefArray = sitePrefList.sitePrefs[i].id.split("||");
            var isCondMatch = false;
            for (var j = 0; j < sitePrefArray.length; j++) {
                  sitePrefQsDevice = sitePrefList.sitePrefs[i].device;
                  sitePrefQsValue = sitePrefList.sitePrefs[i].value;

            }
}

if (sitePrefQsValue != '') {
			changeSitePref(sitePrefQsValue);
			siteDetermined = true;
        }

Open in new window


I have a device check script which works ok and returns either mobile or desktop
function deviceCheck() {
    var deviceType = '';
    if (jQuery.browser.mobile) {
        deviceType = "mobile";
        return deviceType
    }
    else {
        deviceType = "desktop";
        return deviceType
    }
}
