The onerror Event
JavaScript Objects
This instance object has properties, methods, and events. You can also access
the instancetypes array.
For documentation of the methods, properties, and events, see ”Instances Object”
on page 9.
Note that, for the instance object’s onerror event,
• usually only the source property is available
• the event only fires if the save method fails
If the status of the eWebEditPro object is EWEP_STATUS_SIZEEXCEEDED,
two additional event properties are available to help troubleshoot the error.
• contentSize - the number of characters in the content
• maxContentSize - the maximum number of characters permitted, as
specified by the maxContentSize parameter (See “Property:
maxContentSize” on page 130.)
Here is an example of how to use these properties.
function myOnErrorHandler()
{
if (EWEP_STATUS_SIZEEXCEEDED == this.status && "save" == this.event.source)
{
var strMsg = "HTML content size (in chars): " + this.event.contentSize + "
Maximum: " + this.event.maxContentSize;
alert(strMsg);
}
}
eWebEditPro.instances.MyContent1.onerror = myOnErrorHandler; //
The instanceTypes Array
Note that you cannot use ...onerror = "myOnErrorHandler()"; .
You can list all possible editor types by accessing the eWebEditPro JavaScript
Object's instanceTypes array. For example:
document.write("Instance Types:");
for (var i = 0; i < eWebEditPro.instanceTypes.length; i++)
{
document.write("&nbsp;&nbsp;" + eWebEditPro.instanceTypes[i].type + "");
}
Also, you can use the instanceTypes Array to determine which type of editor to
create. For example, to prevent the ActiveX-based editor from being created,
assign a false value to this syntax:
instanceTypes["activex"].isSupported
If set to true, ActiveX is supported.
