Passing additional arguments to a JavaScript function in addition to DOMId

[rsprik]

I have a successful implementation of a seating chart solution using DragNode. I'm just trying to learn more about the JavaScript semantics to code more efficiently and advance my own learning...

 

 

 

JavaScript function:

 

function updateChartfoo(DOMId){

 

//Get reference to chart object using Dom ID

 

var chartObj = getChartFromId("MyChart");

 

var suffix = 'foo';

 

//Update it's URL

 

chartObj.setDataURL("/MyXML_" + suffix + ".xml");

 

 

 

Later in the HTML there's a button... including this:

 

onclick="javaScript:updateChartfoo();"

 

 

 

I have 3 different XML source files... let's call them:

 

MyXML_foo.xml

 

MyXML_bar.xml

 

MyXML_blort.xml

 

 

 

I'm trying to create one function to make the code efficient, but I could not figure out how to pass along the value I want to assign the suffix variable from the onclick event.

 

 

 

I tried updateChart(foo);

 

 

 

and then in the function I started with:

 

updateChart(DOMId,suffix)

 

.... and other variations.... none of which worked

 

 

 

Sorry, my JS skills aren't where they need to be and so for now I had to settle for creating three different functions.

 

 

 

Is there any way to pass along additional arguments to the updateChart(DOMId) function from the onClick trigger?

 

 

 

Thanks!

surely,

What was missing was that the onclick events will pass the suffix values ..tahts a must...

and the function receiving that sufix value in proper order...i mean see the example below..we are passing the suffix as second argument, hence we will receive as seceond agrument in the functon declaration .... for 3 different suffixes we will need 3 links..

all you need to do are :

HTML part : 1. onclick="updateChart('ChartId1','foo');"

2.onclick="updateChart('ChartId1','bar');"

3.onclick="updateChart('ChartId1','blort');"

JAvascript part :

function updateChart(DOMId,suffix){

var chartObj = getChartFromId("MyChart");

chartObj.setDataURL("/MyXML_" + suffix + ".xml");
