Business Logic JavaScript Function Declarations |
Enter a function call using JavaScript. The function is called when an update is submitted from the mobile device. See below for example code. |
Following is a sample function that is called when cells are displayed on a mobile device.
// This function will be called whenever each cell data
// is drawn
// cellValue : value of the data cell
// function evaluateFunction(cellValue)
{
// cellValue is the value of the cell to be printed
// The following show an example of changing the data
// cell font color
// to red and adding a link to call alertFunction when
// click on
// uncomment out to use
/*
createElement("A");
eleHref.href = "#";
eleHref.onclick = alertFunction;
eleHref.style.color = "#FF0000";
eleHref.appendChild( document.createTextNode( cellValue ) );
return eleHref;
*/
// return string or DHTML object to be replaced
// return cellValue;
}
// uncomment this out to use
/*
function alertFunction()
{
// the reference to this is the object declared to
// this function
var obj = this;
// This will return the text that is clicked on
var txt = obj.childNodes[0].nodeValue;
alert("I have clicked on : " + txt);
// If you want to show status or alert at the
// bottom of the grid table use the following
// showCustomData("My text here : " + txt);
}
*/
In this example, when the user clicks a cell, the cell content is displayed in red (#FF0000) and the status or alert displays at the bottom of the grid table.
