javascript alert not showing up
Posted on 2013-01-17
I can set a breakpoint on the alert th see that it does indeed get fired, but it never shows up.
function btnScan_onclick(divToRefresh)
{
TheDivToRefresh = divToRefresh;
WebTWAIN.IfShowUI = false;
IfDisableSourceAfterAcquire = true;
WebTWAIN.AcquireImage();
if (WebTWAIN.HowManyImagesInBuffer == 0){
Alert('No image was scanned');
Return();
}
}

Check your javascript console output. It will tell you if you have errors. It's possible it's bombing out on something else before getting to this...especially if the javascript had a fatal exception due to missing terminators etc.

if (WebTWAIN.HowManyImagesInB
alert('No image was scanned');
Return(); // is this a function or the keyword? all javascript keyword are lowercase : return;
}
}
alert('No image was scanned');
function btnScan_onclick(divToRefre
{
TheDivToRefresh = divToRefresh;
WebTWAIN.IfShowUI = false;
IfDisableSourceAfterAcquir
WebTWAIN.AcquireImage();
if (WebTWAIN.HowManyImagesInB
alert('No image was scanned');
Return(); // is this a function or the keyword? all javascript keyword are lowercase : return;
}
}
