Javascript function error : URGENT HELP
Hi,
I have a problem with javascript functions. I really need your help asap.
I have two functions. printArray() & nextRecords().
I'm passing parameters between these two functions.
printArray() is displaying first 5 elements of Array . Then this function has 'Next' button . If I click 'Next' button , it calls nextRecord() & it displays next 5 records. Again if I click 'Next' button It displays next 5 records & so on.
I'm able to display next 5 records only if i hit 'Next' button first time. If I click it again it is saying 'object not found' because it is generating new HTML page & It is not able to find nextRecord function.
In short I want to dispaly contents of Array pagewise. How can I display it?
Please I'm in badly need.
Thanks in advance.

Hi,
My functions are like this. Could you please tell me where should I put this array in hidden var?
function printArray(mStartIndex,mEndIndex,mDataArray)
{
pStartIndex = mStartIndex;
pEndIndex = mEndIndex;
pDataArray = mDataArray;
document.writeln('<HTML>');
document.writeln('<TABLE BORDER = 1>');
for( var i = pStartIndex; (i < pEndIndex) && (i < pDataArray.length); i++)
{
document.writeln('<TR>');
document.writeln('<TD>');
document.writeln(pDataArray);
document.writeln('</TD>');
document.writeln('</TR>');
pStartIndex = i;
}
document.writeln('</TABLE>');
document.writeln('</HTML>');
if(pEndIndex >= pDataArray.length )
{
document.write("Next");
}
else
{
document.write("<input type = 'button' value = 'Next' onClick = 'nextRecords(" + pStartIndex + "," + pEndIndex +")'>");
}
if(pStartIndex <= 0)
{
document.write("Previous");
}
else
{
document.write('<input type = button value = Previous onClick = previousRecords()>');
}
}
function nextRecords(startIndex,endIndex)
{
if (startIndex == 0)
{
}
if ((startIndex > 0) && (startIndex < xArray.length))
{
startIndex = endIndex;
endIndex = startIndex + pSize;
printArray(startIndex,endIndex,xArray);
}
}
// your array variable here
arra
// first page
printArray()
nextRecords(){
// Note using document.write statements
// write your nextRecords function here
// get hidden arra value here
// end your function here
//for loop
document.write( ''' bla ..bla...");
document.write( ''' bla ..bla...");
document.write( ''' bla ..bla...");
//for loop ends here
// write form tag here
document.write( "<input type="hidden" value="+arra+">");
// your next button ..here
// end form tag here
}
hope you got it..

Hi ,
I modified my function but I'm not able to get values in nextRecords function.
I tried to figure it out but couldn't.
I appreciate your help.
function printArray(mStartIndex,mEndIndex,mDataArray)
{
var pStartIndex = mStartIndex;
var pEndIndex = mEndIndex;
var pDataArray = new Array();
pDataArray = mDataArray;
document.writeln('<HTML>');
document.writeln('<HEAD>');
if(flag == true)
{
document.writeln('<script language = javascript>');
document.writeln('function nextRecords(nStartIndex, nEndIndex)');
document.writeln('{');
document.writeln("alert(" + "'Working'" + ");");
document.writeln('var dArray = new Array();');
document.writeln('dArray = document.frm.hiddenDataArray.value;');
document.writeln('document.writeln(dArray.length);');
document.writeln('for( var i = 0; (i < 5) && (i < 14); i++)');
document.writeln('{');
document.writeln('document.writeln("<TR>");');
document.writeln('document.writeln("<TD>");');
document.writeln('document.writeln(dArray);');
document.writeln('document.writeln("</TD>");');
document.writeln('document.writeln("</TR>");');
//document.writeln('nStartIndex = i;');
document.writeln('}');
document.writeln('}');
document.writeln("<" + "/" + "script>");
document.writeln("<" + "/" + "head>");
}
document.writeln('<BODY>');
document.writeln('<FORM NAME = frm>');
document.writeln('<TABLE BORDER = 1>');
for( var i = pStartIndex; (i < pEndIndex) && (i < pDataArray.length); i++)
{
document.writeln('<TR>');
document.writeln('<TD>');
document.writeln(pDataArray);
document.writeln('</TD>');
document.writeln('</TR>');
pStartIndex = i;
}
document.writeln('</TABLE>');
document.writeln('<INPUT TYPE = HIDDEN NAME = hiddenDataArray VALUE = " +pDataArray +" >');
if(eIndex >= xArray.length )
{
document.write("Next");
}
else
{
document.write("<input type = 'button' value = 'Next' onClick = nextRecords(" + pStartIndex + "," + pEndIndex +")>");
}
document.writeln('</FORM>');
document.writeln('</BODY>');
document.writeln('</HTML>');
}
