问题
I've created a JavaScript OnSave event that parses through a "Sales Quota Distribution" entity grid within an "Opportunity" entity form, and checks for duplicates in the "Resource" field of the "Sales Quota Distribution" grid. When there is a duplicate, a warning message will appear. This is working, but I'd like to be able to append the OnSave event to not allow the user to save the form if there are no duplicate resources. How can I do this?
Below is my current code:
function GetTotalResourceCount(executionContext) {
console.log("function started");
var execContext = executionContext;
var formContext = executionContext.getFormContext();
var resourceyescount = 0;
try {
var gridCtx = formContext._gridControl;
var grid = gridCtx.getGrid();
var allRows = grid.getRows();
//get rows - use the getControl method and pass the grid name.
//var gridContext = formContext.getControl("s_qd");
// if (formContext.getGrid().getTotalRecordCount() == 0) {
// setTimeout(function () { GetTotalResourceCount(execContext); }, 2000);
// return;
// }
var duplicatesFound = 0;
//loop through rows and get the attribute collection
allRows.forEach(function (row, rowIndex) {
var thisRow = row.getData().entity;
var thisRowId = thisRow.getId();
var thisResource = "";
var thisResourceName = "";
var thisResourceID = "";
console.log("this row id=" + thisRowId);
var thisAttributeColl = row.getData().entity.attributes;
thisAttributeColl.forEach(function (thisAttribute, attrIndex) {
var msg = "";
if (thisAttribute.getName() == "new_resource") {
thisResource = thisAttribute.getValue();
thisResourceID = thisResource[0].id;
thisResourceName = thisResource[0].name;
}
});
// Loop through every row and find one with
// thatresource == thisResource &&
// thatrow ID != thisRowId
var allRows2 = formContext.getGrid().getRows();
//loop through rows and get the attribute collection
allRows2.forEach(function (row, rowIndex) {
var thatRow = row.getData().entity;
var thatRowId = thatRow.getId();
var thatAttributeColl = row.getData().entity.attributes;
var thatResource = "";
var thatResourceName = "";
var thatResourceID = "";
thatAttributeColl.forEach(function (thatAttribute, attrIndex) {
if (thatAttribute.getName() == "new_resource") {
thatResource = thatAttribute.getValue();
thatResourceID = thatResource[0].id;
thatResourceName = thatResource[0].name;
if (thatResourceID == thisResourceID && thatRowId != thisRowId) {
duplicatesFound++;
var msg = "Duplicate resource " + thatResource;
}
}
});
});
});
if (duplicatesFound > 0) {
console.log("duplicate found");
Xrm.Utility.alertDialog("WARNING: There are duplicate resources in the Sales Quota Distribution grid.");
}
} catch (err) {
console.log('Error occurred :' + err)
}
}
Any help would be greatly appreciated. Thanks!
回答1:
You can also use the setNotification method on one of the controls. This will prevent the form from being saved.
From the documentation:
Setting an error notification on a control will block the form from saving.
So like:
formContext.getControl('your_attributename').setNotification('This will be displayed', 'optional id');

What you need is preventDefault (Client API reference) Few example links here,
Javascript – Prevent Save
Cancelling save event based on the result of async operation
Try below code, I have added just 2 lines var saveEvent = executionContext.getEventArgs();saveEvent.preventDefault();
Assuming your function GetTotalResourceCount(executionContext)
is running onSave Event.
function GetTotalResourceCount(executionContext) {
console.log("function started");
var execContext = executionContext;
var formContext = executionContext.getFormContext();
var resourceyescount = 0;
try {
var gridCtx = formContext._gridControl;
var grid = gridCtx.getGrid();
var allRows = grid.getRows();
//get rows - use the getControl method and pass the grid name.
//var gridContext = formContext.getControl("s_qd");
// if (formContext.getGrid().getTotalRecordCount() == 0) {
// setTimeout(function () { GetTotalResourceCount(execContext); }, 2000);
// return;
// }
var duplicatesFound = 0;
//loop through rows and get the attribute collection
allRows.forEach(function (row, rowIndex) {
var thisRow = row.getData().entity;
var thisRowId = thisRow.getId();
var thisResource = "";
var thisResourceName = "";
var thisResourceID = "";
console.log("this row id=" + thisRowId);
var thisAttributeColl = row.getData().entity.attributes;
thisAttributeColl.forEach(function (thisAttribute, attrIndex) {
var msg = "";
if (thisAttribute.getName() == "new_resource") {
thisResource = thisAttribute.getValue();
thisResourceID = thisResource[0].id;
thisResourceName = thisResource[0].name;
}
});
// Loop through every row and find one with
// thatresource == thisResource &&
// thatrow ID != thisRowId
var allRows2 = formContext.getGrid().getRows();
//loop through rows and get the attribute collection
allRows2.forEach(function (row, rowIndex) {
var thatRow = row.getData().entity;
var thatRowId = thatRow.getId();
var thatAttributeColl = row.getData().entity.attributes;
var thatResource = "";
var thatResourceName = "";
var thatResourceID = "";
thatAttributeColl.forEach(function (thatAttribute, attrIndex) {
if (thatAttribute.getName() == "new_resource") {
thatResource = thatAttribute.getValue();
thatResourceID = thatResource[0].id;
thatResourceName = thatResource[0].name;
if (thatResourceID == thisResourceID && thatRowId != thisRowId) {
duplicatesFound++;
var msg = "Duplicate resource " + thatResource;
}
}
});
});
});
if (duplicatesFound > 0) {
console.log("duplicate found");
Xrm.Utility.alertDialog("WARNING: There are duplicate resources in the Sales Quota Distribution grid.");
var saveEvent = executionContext.getEventArgs();
saveEvent.preventDefault();
}
} catch (err) {
console.log('Error occurred :' + err)
}
}
