dojo利用promise實現多個異步校驗

代碼如下：

// 敏感詞過濾
var promiseAll = checkSenstiveWords();
promiseAll.then(function (results) {
	// console.log("results=>", results)
	// console.log("v1=>", results[0].flag);
	// console.log("v2=>", results[1].flag);
	// console.log("v3=>", results[2].flag);

	if(results[0].flag == true){
		Tip.fail({
			"text": msg["errors.sensitive.word.warn"]
				.replace("{0}", lang["kmsMultidoc.kmsMultidocKnowledge.docSubject"])
				.replace("{1}", '<span style="color:#cc0000">' + results[0].senWords + '</span>')
		});
		return ;
	}
	if (results[1].flag == true) {
		Tip.fail({
			"text": msg["errors.sensitive.word.warn"]
				.replace("{0}", lang["kmsMultidocKnowledge.fdDescription"])
				.replace("{1}", '<span style="color:#cc0000">' + results[1].senWords + '</span>')
		});
		return;
	}
	if (results[2].flag == true) {
		Tip.fail({
			"text": msg["errors.sensitive.word.warn"]
				.replace("{0}", lang["kmsMultidoc.kmsMultidocKnowledge.docContent"])
				.replace("{1}", '<span style="color:#cc0000">' + results[2].senWords + '</span>')
		});
		return;
	}
	
	// 校驗成功
	// do something
}, function () {
	Tip.fail({"text" : lang['mui.return.failure']});
})

具體的校驗方法

window.checkSenstiveWords = function () {
	var docSubject = document.getElementsByName("docSubject")[0].value;
	var fdDescription = document.getElementsByName("fdDescription")[0].value;
	var docContent = document.getElementsByName("docContent")[0].value;
	console.log("docSubject=>", docSubject);
	console.log("fdDescription=>", fdDescription);
	console.log("docContent=>", docContent);

	var suburl = util.formatUrl(self.senstiveValidateUrl);
	var subdata = {"content": encodeURIComponent(docSubject), formName: "kmsMultidocKnowledgeForm"};
	var docSubjectPromise = request.post(suburl, {data: subdata, method: 'POST', handleAs: 'json'});

	var desurl = util.formatUrl(self.senstiveValidateUrl);
	var desdata = {"content": encodeURIComponent(fdDescription), formName: "kmsMultidocKnowledgeForm"};
	var fdDescriptionPromise = request.post(desurl, {data: desdata, method: 'POST', handleAs: 'json'});

	var conurl = util.formatUrl(self.senstiveValidateUrl);
	var condata = {"content": encodeURIComponent(docContent), formName: "kmsMultidocKnowledgeForm"};
	var docContentPromise = request.post(conurl, {data: condata, method: 'POST', handleAs: 'json'});

	return all([docSubjectPromise, fdDescriptionPromise, docContentPromise])
}
