Any one know how to make hardstop in H5 SCRIPT when user enter invalid values.

Hi,

You may use an event to cancel the request that is processing.

You may attach an event called "onRequesting" to catch the event before sending the request.

ex.

private attachEvents(controller: IInstanceController): void {

this.detachRequesting = controller.Requesting.On((e) => {

this.onRequesting(e);

});

this.detachRequested = controller.Requested.On((e) => {

this.onRequested(e);

});

}

private onRequesting(args: CancelRequestEventArgs): void {

// Only validate for the enter key (next button).

if (args.commandType === "KEY" && args.commandValue === "ENTER") {

if (!this.validateFields()) {

args.cancel = true;

}

You just need to pass a true value to cancel the process so that it will not proceed to the next panel.

We too have an H5 Script that has a hard stop. Below is a script that we have that Stop the scrapping of an item if it meets specific criteria:

var MMS240B_stopscrap = /** @class */ (function () {

function MMS240B_stopscrap(scriptArgs) {

this.OrderType = "";

this.controller = scriptArgs.controller;

this.log = scriptArgs.log;

}

MMS240B_stopscrap.Init = function (args) {

new MMS240B_stopscrap(args).run();

};

MMS240B_stopscrap.prototype.run = function () {

var _this = this;

this.unsubscribeRequested = this.controller.Requested.On(function (e) { _this.onRequested(e); });

this.unsubscribeRequesting = this.controller.Requesting.On(function (e) { _this.onRequesting(e); });

};

MMS240B_stopscrap.prototype.onRequesting = function (args) {

args.cancel = false;

if (args.commandType == "LSTOPT" && args.commandValue == "33") {

if (ListControl.ListView.SelectedItem().length > 0) {

var asidval = ListControl.ListView.GetValueByColumnName("ASID")[0];

var statval = ListControl.ListView.GetValueByColumnName("STAT")[0];

if (asidval !== "" && statval == "90") {

ConfirmDialog.ShowMessageDialog({ dialogType: "Error", header: "ERROR", message: "Not Allowed - FA sold or disposed" });

args.cancel = true;

}

}

}

};

MMS240B_stopscrap.prototype.onRequested = function (args) {

this.unsubscribeRequesting();

this.unsubscribeRequested();

};

return MMS240B_stopscrap;

}());

Hi,

Thanks for reply. I am attaching part of my script but somehow it is not working, I am using M3 API

private onRequesting(args: CancelRequestEventArgs): void {

this.log.Info("onRequesting");

// this.executeByRequest();

//-------------------------------------ATS020MI / LstAttribute--------------------------------------------------------------------

const myRequest = new MIRequest();

let message: string;

var Company = "114";

myRequest.program = "ATS020MI";

myRequest.transaction = "LstAttrValue";

//Fields that should be returned by the transaction

myRequest.outputFields = ["ATID", "OBV1", "AALF"];

myRequest.includeMetadata = true;

myRequest.typedOutput = true;

myRequest.maxReturnedRecords = 0;

myRequest.timeout = 60000;

//Input to the transaction

var atav = ScriptUtil.GetFieldValue("WWATAV");

var atid = ScriptUtil.GetFieldValue("WWATID");

var aalf = ScriptUtil.GetFieldValue("WWAALF");

// var atav = "0100";

myRequest.record = { ATID: atid.trim() };

MIService.Current.executeRequest(myRequest).then(

(response: IMIResponse) => {

//Read results here

for (let item of response.items) {

this.log.Info(`1: ATID : ${item.ATID}`);

this.log.Info(`1: Option : ${item.OBV1}`);

this.log.Info(`1: FromValue1 : ${parseInt(item.AALF)}`);

this.alaf = item.AALF;

this.vtav = ScriptUtil.GetFieldValue("WWATAV");

this.obv1 = item.OBV1;

if (item.AALF != null) {

if (parseInt(item.AALF) == parseInt(atav.trim())) {

message = item.ATID + " " + " Valid VaLue " + parseInt(item.AALF) + " " + atav.trim();

ConfirmDialog.Show({

header: "Attribute Model",

message: message,

dialogType: "Information",

})

};

== Following error message is display but it is still not stoping the screen it is going to next screen =====

if (args.commandType === "KEY" && args.commandValue === "ENTER") {

if (parseInt(item.AALF) != parseInt(atav.trim())) {

args.cancel = true

ConfirmDialog.ShowMessageDialog({ dialogType: "Error", header: "ERROR", message: "Not Allowed - Invalide Value" });

//args.cancel = true;

}

}

}

}

}).catch((response: IMIResponse) => {

//Handle errors here

// args.cancel = true;

this.log.Error(response.errorMessage);

});

=======================I have entered again but it is not stopping the SCREEN

if (args.commandType === "KEY" && args.commandValue === "ENTER") {

if (parseInt(aalf) != parseInt(atav.trim())) {

args.cancel = true

ConfirmDialog.ShowMessageDialog({ dialogType: "Error", header: "ERROR", message: "Not Allowed - Invalide Value" });

}

}

}

Hi JayP,

Does your MI request need to happen after doing an action(ex. change, display)?

If the request doesn't need to do this step, you may put it when the script runs the first time, and get the values you need and store it somewhere.

I tried to mock the process, since the MI request has a call back function, both the request and the regular post data action runs at the same time, that's why it is not cancelled. (you may look at this in Fiddler).

Hi Reggie,

Thanks for reply, But Yes Once user enter the value in field , I need to trigger an API to retrieve the valid values and I need to validate the entered value with API result and if validation is failed then I need to show the error message with hard stop.

You can always control the ENTER key.

However it's possible to skip that validation if You don't block the user key action when user access to screen of after a refresh (F5)...
