I recently had a need to reuse query string values multiple times on a page.
Calling a function that parses the query string each time just isn’t efficient.
I decided to use a self-executing function I wrote that stores the values as properties of an object.
We’ve all been there, we need to get those query string values using JavaScript – then we think, I’ve done this before — but how did I do it. I know the code is around here somewhere…
I prefer to have values stored once to be accessible as needed.
This function:
- Self-executes
- Checks if a query string exists
- Extracts the fields and values from that string
- Decodes the values if they are URI encoded
- Creates a global object
- Checks to make sure the value used to name a property is alphanumeric
- Adds a property and value to the object for each field/value pair from the query string
I’m using an object name of QS. You can rename this to whatever suits your needs.
Example URI encoded query string
?client%3DJack%20Burton%20Clothing%20Inc.%26project%3DPork%20Chop%20Express%20Redesign
Non-encoded it would read:
?client=Jack Burton Clothing Inc.&project=Pork Chop Express Redesign
JavaScript
This is a self-executing function – meaning you do not have to call it. It will execute when the code is loaded.
(function(){
//decode and remove first question mark
var qStr = decodeURIComponent(location.search).replace(/\?/,"")
//if query string empty
if(qStr === ""){return false}
//split to array
qStr = qStr.split("&")
//create global object
QS = {}
for(i=0;i<qStr.length;i++){
var e = qStr[i].split("=")
//property name - strip all but basic alphanumeric
e[0] = e[0].toString()
.toLowerCase()
.replace(/[^a-zA-Z0-9]+/g,'')
//property value - replace plus sign with blank space
e[1] = e[1].replace(/\+/g,' ')
//assign properties and values to object
QS[e[0]] = e[1]
}
})()
You can access the values in the following ways:
QS.client QS.project QS["client"] QS["project"]
* In super-rare cases where a numeric value is used for a field name, ex. ?1=apple, you cannot access via dot notation, you will have to use QS["1"].
In action:
//JavaScript
document.getElementById("client").innerHTML=QS.client
//jQuery
$("#client").html(QS.client)
You can even take it a step further and add the function to an existing or new namespace. You can then access it via that namespace using dot notation.
For the following example we will create a namespace called “MYSITE”. To this namespace we will add a child object called “qs”. This child object will hold the result/values of our function.
The code is slightly different from above in that it does not create a global object named “QS”. Instead it adds the object “qs” to the “MYSITE” namespace and the function returns the result to the “qs” object.
JavaScript(namespaced)
if(typeof MYSITE==="undefined" || !MYSITE) MYSITE={};
MYSITE = {
qs: (function(){
//decode and remove first question mark
var qStr = decodeURIComponent(location.search)
.replace(/\?/,"")
//if query string empty
if(qStr === ""){return false}
//split to array
qStr = qStr.split("&")
//create global object
var QS = {}
for(i=0;i<qStr.length;i++){
var e = qStr[i].split("=")
//property name - strip all but basic alphanumeric
e[0] = e[0].toString()
.toLowerCase()
.replace(/[^a-zA-Z0-9]+/g,'')
//property value - replace plus sign with blank space
e[1] = e[1].replace(/\+/g,' ')
//assign properties and values to object
QS[e[0]] = e[1]
}
//return object
return QS
})()
}
You can access the values in the following ways:
MYSITE.qs.client MYSITE.qs.project MYSITE.qs["client"] MYSITE.qs["project"]
In action:
//JavaScript
document.getElementById("client").innerHTML=MYSITE.qs.client
//jQuery
$("#client").html(MYSITE.qs.client)
I hope you find this bit of reusable code helpful.
