Save button using SSJS does not open xe:dialog in web xpage but works on mobile xpage

问题

The following save button code works well on mobile xpage:

var checkBox31:com.ibm.xsp.component.xp.XspInputCheckbox = getComponent("checkBox31");
var customerID1:com.ibm.xsp.component.xp.XspInputText = getComponent("customerID1");
var a = checkBox31.getValue();
var b = customerID1.getValue()
if (a == "" || a == null){
   if (b == ""){
   sessionScope.put("ITDialog","You must enter Customer ID");
   var dialog1:com.ibm.xsp.extlib.component.dialog.UIDialog = getComponent("dialog1");
    dialog1.show();
   }
   }

But it does not work on web xpage. I'm using 8.5.3FP6. I used 8.5.3FP1 and 8.5.3FP5 bu had same issue.

Thanks in advance for any help.

Here is sample of code which is not working.

回答1:

A checkbox has a value of either 'false' or 'true' (indicating it is 'deselected' & 'selected'), it shouldn't return a value of "" or null. Therefore, the first if statement is never true, and your dialog will never appear.

I believe what you want is that if the checkbox is unselected, there must be a customer ID entered in the input. If so, I think this is the code you want:

var checkBox31:com.ibm.xsp.component.xp.XspInputCheckbox = getComponent("checkBox31");
var customerID1:com.ibm.xsp.component.xp.XspInputText = getComponent("customerID1");
var a = checkBox31.getValue();
var b = customerID1.getValue();
if (a == "false") {
    if (b == "") {
        sessionScope.put("ITDialog","You must enter Customer ID");
        var dialog1:com.ibm.xsp.extlib.component.dialog.UIDialog = getComponent("dialog1");
        dialog1.show();
    }
}
