Can someone explain how to persist global variables in the following situation? The on save method in this code will throw an error of 'undefined'.

SomeDataValue = "Hello";

function OnFormLoad(executionContext) {

}

function OnFormSaved(executionContext) {

alert(SomeDataValue);

}

Hi JFulfordMS,

You need to declare the SomeDataValue variable.

var SomeDataValue = "Hello"; function OnFormLoad(executionContext) { } function OnFormSaved(executionContext) { alert(SomeDataValue); }

Hi,

You can also use shared variable in your Javascript to pass data between different event.

See below link for more details.

docs.microsoft.com/.../setsharedvariable

ExecutionContextObj.setSharedVariable(key, value)

ExecutionContextObj.getSharedVariable(key)

As suggested in above post you should declare your variable using var keyword then it will work.

That seems to have worked. Still seeing some unusual behavior though. I'm doing some testing and will post findings back shortly.

Bipin, that actually didn't work. The variables didn't persist to the executionContext passed to the onsave event.

The issue I was facing was that the variables were staying 'undefined'. Take the following example.

var variableOne = false; var variableTwo = false; function OnLoad(executionContext) { formContext.getAttribute("my_variableOne").addOnChange(VariableOneChanged); formContext.getAttribute("my_variableTwo").addOnChange(VariableTwoChanged); } function VariableOneChanged(executionContext) { variableOne = true; } function VariableTwoChanged(executionContext) { variableTwo = true; } function OnSave(executionContext) { alert("VariableOne is: " variableOne); alert("VariableTwo is: " variableTwo); }

In this example, assume that only the variableOne field has been changed.

The output of this example would be.

VariableOne is: true

VariableTwo is: undefined
