JavaScript Multiple Functions With Returns Passing Values.

Question

0.00/5 (No votes)

See more:

I have created 3 JavaScript Functions. The 1st 2 will return 2 values and I want the 3rd function to grab those values.

JavaScript

function retStartDate(){
var strStartDate = document.getElementById("from_date").value;
alert(strStartDate);

return strStartDate;

}

function retEndDate(){
var strEndDate = document.getElementById("to_date").value;
alert(strEndDate);
return strEndDate;

}

function getVaria(){

var strWsUrl = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&filters=ga%3Asource!%3D(direct)&sort=-ga%3Ausers&start-date= retStartDate() &end-date= retEndDate() &max-results=10';

alert(strWsUrl);

return strWsUrl;

}

Now you can see getVaria() has a variable strWsUrl & in that I have placed the 2 functions that return strStartDate & strEndDate as the below.

JavaScript

var strWsUrl = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&filters=ga%3Asource!%3D(direct)&sort=-ga%3Ausers&start-date= retStartDate() &end-date= retEndDate() &max-results=10';

But when I alert that I got the follwoing result.

https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&filters=ga%3Asource!%3D(direct)&sort=-ga%3Ausers&start-date= retStartDate() &end-date= retEndDate() &max-results=10

But the correct alert must be with two dates for start-date & end-date.

Can you someone guess what I have done wrong? If so please try to post the solution.

Thanks & regards,
Chiranthaka.

Hi Sampath,

It is because you are not calling your javascript functions.The alert shows your strWsUrl as it is.So, you can do something like this.Call two of your javascript functions like below

C#

function getVaria(){

var strWsUrl = 'https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A76546294&dimensions=ga%3Asource&metrics=ga%3Ausers&filters=ga%3Asource!%3D(direct)&sort=-ga%3Ausers&start-date= '+ retStartDate() + '&end-date=' + retEndDate() + '&max-results=10';

alert(strWsUrl);

return strWsUrl;

}

Hope this help :-)
