Javascript: 1st part Checks URL for queries.

You will need to adjust for your URLs.

////////1st part
*Check Query Strings on URLs*
function getQueryVariable(variable) {
var query = window.location.search.substring(1)
var vars = query.split(“&”);
var blank = “blank”
for (var i=0;i<vars.length;i++) {
var pair = vars[i].split(“=”)
if(pair[0] == variable){
if(pair[1].indexOf(‘%20’) != -1){
console.log(pair[1].indexOf(‘%20’))
var fullName = pair[1].split(‘%20’)
console.log(fullName)
return fullName[0] + ‘ ‘ + fullName[1]
}
else {
return pair[1];

}
}
}
return(false)
}

/////////2nd part
