我有一个sapui5应用程序:
我有一个名为“Submission.view和相应的控制器”的xml视图,名为“submission.controller”。
我的方法是使用某些输入参数从服务中获取一些问题ID。
例如,如果我传递“null”和“previous”,它会给我一个json响应:
[
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 51,
"YesNo": "",
"Mandatory": false
},
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 52,
"YesNo": "",
"Mandatory": false
},
{
"__type__": "QuestionOutput",
"QuestionType": "",
"QuestionID": 53,
"YesNo": "",
"Mandatory": false
}
]
现在我想将每个像51,52,53这样的问题传递给另一个方法,该方法调用休息服务从hana数据库中获取上述问题的描述。
getBpmRules: function(sToken, sQuestionId, sAnswer) {
var that = this;
this.showBusy();
jQuery.ajax({
type: "POST",
contentType: "application/json",
dataType: "json",
async: false,
url: "/bpmrulesruntime/rules-service/v1/rules/invoke?rule_service_name=SelfServiceRule::QuestionRuleService",
context: that,
xhrFields: {
withCredentials: true
},
headers: {
'X-CSRF-Token': sToken
},
data: JSON.stringify([{
"__type__": "QuestionInput",
"QuestionID": "" + sQuestionId + "",
"Answer": "" + sAnswer + ""
}]),
error: function(jqXHR, textStatus, errorThrown) {
that.hideBusy();
sap.m.MessageBox.alert(textStatus + " - " + errorThrown + " : " + jqXHR.responseText, {
icon: sap.m.MessageBox.Icon.ERROR,
title: this.getText("error")
});
},
success: function(data, textStatus, jqXHR) {
var questiondesc = [];
if (data.length !== 0) {
var desc = [];
//this.getModel("questionModel").setProperty("/questionDescription", data);
for (var i = 0; i < data.length; i++) {
desc = that.getQuestionDescriptionById(data[i].Question, sToken);
}
}
that.hideBusy();
this._oManagerBusy.setVisible(false);
this._showSendDialog();
}
});
}
获取json数据后,我只是循环并将问题ID传递给另一个方法来获取每个问题的描述,这也是json响应。
getQuestionDescriptionById: function(id, token) {
jQuery.sap.log.debug("Getting question by Id");
var questionDescription = [];
this.getComponent().ajax({
method: "GET",
url: "/selfservice/rest/question/admin/questionid/" + id,
contentType: "application/json",
context: this,
headers: {
'X-CSRF-Token': token
},
error: function(jqXHR, textStatus, errorThrown) {
this.getModel("resources").setProperty("/ticketSubmitMessage", this.getModel("i18n").getProperty("sendDialogText"));
this._oManagerBusy.setVisible(false);
this._showSendDialog();
},
success: function(data, textStatus, jqXHR) {
//oModel.loadData(“json/Item.json”);
// this.getView().setModel(new JSONModel(data.question,"questionDescription"));
if (data.length !== 0) {
questionDescription.push(data);
}
}
});
return questionDescription;
},
问题:
我无法使用我从第二种方法获得的json响应为视图设置模型,因为对于每个questionid,它转到下一个方法“getQuestionDescriptionById”,即使我返回响应..也没有不行。
请告诉我如何为每个问题ID获得的每个响应设置一个json模型。
谢谢!
