LS table how it works

[betasec]

Hi ,
i develop some pages with LS and i need to create on the same page many tables with data , i use servlet to print my table the tab OverwriteTable and pushPage

as here everything is ok, only if i use formatValues function inside the servlet on the same <Script> </Script> tags
when i put the formatValues on a separate <Script> </Script> tags then its not working
i need to print my tables from servlet and use format functions from js
so to use the same format.js for all pages

SOME EXAMPLE

****************************************************************************
THIS WORKING

<Script Language="JavaScript">
//////////////// Stock Table Management
// create an OverwriteTable; item and field names will be grabbed from
// the corresponding HTML divs
var table = new OverwriteTable(null, null, "MERGE");

table.setDataAdapter("My_Adapter");
table.setSnapshotRequired(true);
table.onChangingValues = formatValues;

// bind the table to the corresponding HTML divs
pushPage.addTable(table, tableID);

function formatValues(itemPos, visualUpdateInfo, itemName) {
if (visualUpdateInfo != null) {
var cold = (itemPos % 2 == 1) ? "#eeeeee" : "#ddddee";
visualUpdateInfo.setRowAttribute("yellow", cold, "backgroundColor");
}
}
</script>

THIS NOT WORKING

<Script Language="JavaScript">
//////////////// Stock Table Management
// create an OverwriteTable; item and field names will be grabbed from
// the corresponding HTML divs
var table = new OverwriteTable(null, null, "MERGE");

table.setDataAdapter("My_Adapter");
table.setSnapshotRequired(true);
table.onChangingValues = formatValues;

// bind the table to the corresponding HTML divs
pushPage.addTable(table, tableID);
</script>

SOME CODE HERE

<Script Language="JavaScript">
function formatValues(itemPos, visualUpdateInfo, itemName) {
if (visualUpdateInfo != null) {
var cold = (itemPos % 2 == 1) ? "#eeeeee" : "#ddddee";
visualUpdateInfo.setRowAttribute("yellow", cold, "backgroundColor");
}
}
</script>

Hi,

in your second example you're assigning to onItemUpdate a value that at that moment is undefined, that's why it does not work.
Each <script> element is executed as soon as it is parsed; note that during the parsing phase functions inside the element are created, that's why the first example correctly work even if formatValue is declared below the piece of code that "uses" it (table.onChangingValues = formatValues; )

There are several ways you can rewrite the code to let it work, just be sure that when you use something it already exists;
e.g.: you may include the format.js above the "new OverwriteTable" code.
