A simple summary of front-end js access to back-end interface data

When the front-end accesses back-end interface data, the beginners who are just getting started basically use the following structure to access:

function m1(){
   $.ajax({
    	type: 'post',
		url: basePath+"/interface/get?outsys=roma&name=asdf",
		data:{
		    params:{}
		},
		success: function(result) {
			console.log(result);
			eval('initChart_' + name + '(result)');
		}
	});
}

Above I call it the bulk js method, so if there are multiple interfaces that need to be docked, there will be multiple such bulk function();

After the upgrade, take a project as an example:

/**
 * 事项列表
 */
var sxml_list = function(){
	
	/**
	 * 接口集
	 * 包含每个图表,的测试地址和正式地址
	 */
	var apiArray = {
		"0":{"url":"getEventList","params":{},"testUrl":"","desc":"根据条件筛选事项列表"},
		"1":{"url":"getEventDetailByConfidition","params":{},"testUrl":"","desc":"根据条件筛选事项详情"},
		"2":{"url":"oneEventHasManyDuty","params":{"name":""},"testUrl":"","desc":"一事多责"}
	}
	
	
	var initChart_0 = function(result){
		console.log(result);
		var data = result.retJSON.result.retJSON.result;
		$('#row_count').text(data.length);
		$("#list").empty();
		if(data.length>0){
			let htmlstr = '';
			$.each(data,function(i,n){
				htmlstr += '<tr class="tr" eventId='+data[i].事项id+' >';
				htmlstr +=   '<td>'+(i+1)+'</td>';
				htmlstr +=   '<td>'+data[i].事项名称+''+(data[i].事项简述==null?'':'--'+data[i].事项简述)+'</td>';
				htmlstr += '</tr>';
				$("#list").html(htmlstr);
			});
			//将拼接好的字符串追加到tbody中
			$('.tr').bind('click',function(){
				sxml_list.apiArray['1'].params.eventId = $(this).attr('eventId');
				setTimeout(function(){
					sxml_list.init('1',true);
				},300);
				if($(this).hasClass('heighlight')){
					$(this).removeClass('heighlight');	
					return;
				}
				$('.tr').removeClass('heighlight');
				$(this).addClass('heighlight');
			})
		}
	}
	
	var initChart_1 = function(result){
		var data = result.retJSON.result;
		
		$("#sxmc").html(data[0].事项名称+''+(data[0].事项简述==null?'':'--'+data[0].事项简述));
//		$("#sxbm").html(data[0].事项编码)
//		$("#sxjs").html(data[0].事项简述)
		$("#glzr").html(data[0].部门名称)
		$("#glzt").html(data[0].部门名称)
		$("#glyj").html(data[0].管理依据==null?'--':data[0].管理依据)
		
		$("#ysdz").html(data[0].是否一事多责==null?"处理流程":"一事多责");
		
		data[0].是否一事多责==null?(show0()):(show())
		
		$("#sxlx").html(data[0].事项名称)
		$(".one-item").html("");
		
		//展示流程
		function show0(){
			$('.right .body .process').show();
			$(".one-n").hide();
			$("#czls").html(data[0].部门名称)
//			$("#glzt").html(data[0].部门名称)
		}
		
		//展示一事多责
		function show(){
			$('.right .body .process').hide();
			$(".one-n").show();
			sxml_list.apiArray['2'].deptName = data[0].部门名称+data[0].事项简述;
			sxml_list.apiArray['2'].params.name = data[0].事项名称;
			sxml_list.init('2',true);
		}
	}
	
	var initChart_2 = function(result){
		var data = result.retJSON.result;
		var oneData = [];
			
		if(data.length>0){
			for(var i in data){
				oneData.push({
					name:data[i].resume,
					bm:data[i].deptname
				})
			}
		}
		one_item_load(oneData);
	}
	
	//****获取数据接口***
	var getAjaxSources = function(name,dataType){
		if(dataType){
			return basePath+"/interface/get?outsys=roma&name="+apiArray[name].url;
		}else{
			return basePath+apiArray[name].testUrl;
		}
	}
	
	var init = function(name,dataType){
		try {
			/*统一访问*/
			var ajaxSources = getAjaxSources(name,dataType);
			$.ajax({
				type: 'post',
				url: ajaxSources,
				data:{
					params:JSON.stringify(apiArray[name].params)
				},
				success: function(result) {
					console.log(result);
					eval('initChart_' + name + '(result)');
				}
			});
		} catch(e) {}
	}
	
	return{
		init:init,
		apiArray:apiArray
	}
}();

In this way, the interface, variables, and the ajax for obtaining the back-end are separated and unified into one object for management. The code structure is clear and clear, and the reusability is relatively high.

The above is just a small summary of the work.

Friends with better code structure and optimization suggestions are welcome to leave a message.
