根据触发用户事件的上下文限制执行
在 SuiteScript 1.0 中,我们使用 nlapiGetContext().getExecutionContext()
检索当前执行上下文,然后我们将结果与适当的原始字符串进行比较。
// 1.0 in Revealing Module pattern
var myNamespace = myNamespace || {};
myNamespace.example = (function () {
var exports = {};
function beforeLoad(type, form, request) {
showBonusEligibility(form);
}
function showBonusEligibility(form) {
// Doesn't make sense to modify UI form when the request
// did not come from the UI
var currentContext = nlapiGetContext().getExecutionContext();
if (!wasTriggeredFromUi(currentContext)) {
return;
}
// Continue with form modification...
}
function wasTriggeredFromUi(context) {
// Current context must be compared to raw Strings
return (context === "userinterface");
}
function isEligibleForBonus() {
return true;
}
exports.beforeLoad = beforeLoad;
return exports;
})();
在 SuiteScript 2.0 中,我们通过导入 N/runtime
模块并检查其 executionContext
属性来获取当前执行上下文。然后,我们可以将其值与 runtime.ContextType
枚举的值进行比较,而不是将原始字符串进行比较。
// 2.0
/**
* @NScriptType UserEventScript
* @NApiVersion 2.x
*/
define(["N/ui/serverWidget", "N/runtime"], function (ui, runtime) {
var exports = {};
function beforeLoad(scriptContext) {
showBonusEligibility(scriptContext.form);
}
function showBonusEligibility(form) {
// Doesn't make sense to modify the form if the
if (!wasTriggeredFromUi(runtime.executionContext)) {
return;
}
// Continue with form modification...
}
function wasTriggeredFromUi(context) {
// Context can be compared to enumeration from runtime module
return (context === runtime.ContextType.USER_INTERFACE);
}
exports.beforeLoad = beforeLoad;
return exports;
});
