常用前端函数
前端扩展开发指导
通过图片来理解界面上元素分别是由什么model构成，在需要对相关控件进行扩展时， 调用相应model的方法及事件。
前端扩展开发指导
Model常用方法
常用前端函数
页面初始化->设置默认值（前端函数）
function (event) {
viewModel.get('userid').setValue(newPseudoGuid());
viewModel.get('startdate').setValue(formatDate(new Date()));
function formatDate(date){
var month = date.getMonth()+1;
return date.getFullYear()+"-"+month+"-"+date.getDate()
}
}
初始化自定义按钮绑定点击事件
function (event) {
var viewModel = this;
viewModel.get('button5ad').on('click', function () {
var rows = viewModel.getGridModel().getSelectedRows();
console.log(rows);
})
}
保存前校验
function (event) {
var viewModel = this;
//设置保存前校验
viewModel.on("beforeSave", function(args){
var jieyongriqi = viewModel.get("jieyongriqi").getValue();
var guihairiqi = viewModel.get("guihairiqi").getValue();
const isAfterDate = (dateA, dateB) => dateA > dateB;
if(!isAfterDate(guihairiqi, jieyongriqi)){
cb.utils.alert("归还日期要大于借用日期")
return false;
}
})
}
列表批量删除及表格行删除
绑定到列表初始化函数里面
function (event) {
var viewModel = this;
viewModel.on('beforeBatchdelete',function(params){
var check = true;
var selected = JSON.parse(params.data.data);
selected.forEach((row)=>{
//row循环的行数据
if('2' ==row.new1){
check = false;
return;
}
});
return check;
});
}
卡片页面删除
function (event) {
var viewModel = this;
viewModel.on('beforeDelete',function(params){
var data = JSON.parse(params.data.data);
if('2' ==data.new1){
return false;
}
});
}
删行前弹出确定框
function (event) {
var viewModel = this;
viewModel.on("beforeDeleteRow",function (args) {
var returnPromise = new cb.promise();//同步
cb.utils.confirm('确定要停用吗？', function(){ //默认异步
//获取选中行
var data = viewModel.getGridModel().getRows()[args.data[0]];
return returnPromise.resolve();
},function (args) {
cb.utils.alert("点击了取消");
returnPromise.reject();
});
return returnPromise;
});
}
表格选中行
function (event) {
var viewModel = this;
var gridModel = viewModel.getGridModel();
gridModel.on('afterSelect', function (data) {
cb.utils.alert(data);
});
}
表格自定义按钮获取选中行数据
function (event) {
var viewModel = this;
viewModel.get('button5vf').on('click', function (args) {
var currentRow = viewModel.getGridModel().getRow(args.index);
})
}
卡片界面枚举清空及设置默认值
//ListModel方法及事件
var sexModel=viewModel.get("sex"); //获取ListModel
sexModel.clear();//ListModel清空方法
sexModel.setValue(2); //ListModel设值
动态设置控件状态
function (event) {
var viewModel = this;
var param = viewModel.get("new1");
param.setState("bIsNull",false);
cb.utils.alert(param);
}
表格里面的参照实现过滤
function (event) {
var viewModel = this;
var girdModel = viewModel.getGridModel();
girdModel.getEditRowModel().get('ref1022_id').on('beforeBrowse', function (data) {
var condition = {
"isExtend": true,
simpleVOs: []
};
condition.simpleVOs.push({
field: 'new1',
op: 'eq',
value1: 11
});
this.setFilter(condition);
});
}
监听图片改变事件
function (event) {
var viewModel = this;
var picture = viewModel.get("tupian");
picture.on('onChange',function(date){
filelist = date.fileList;
console.log(filelist);
});
}
参照框确定按钮监听事件
var ref = viewModel.get('ref_name');
ref.on('afterReferOkClick',function(data){
//参照选择的数据
console.log(data);
})
触发打开另一个单据页面
function (event) {
var viewModel = this;
let data = {
billtype: 'Voucher',// 单据类型
billno: '68081b7b',// 单据号
params: {
mode: 'add', // (编辑态、新增态、浏览态)
},
};
cb.loader.runCommandLine('bill', data, viewModel);
}
查询区动态设置默认值并过滤
function (event) {
var viewModel = this;
var bh = viewModel.get("params").abnormalevent;
viewModel.on('afterMount', function(){
// 获取查询区模型
const filtervm = viewModel.getCache('FilterViewModel');
filtervm.on('afterInit', function () {
// 进行查询区相关扩展
filtervm.get('abnormalevent').getFromModel().setValue(bh);
});
});
}
设置表格整行禁用
var gridModel = viewModel.getGridModel();
gridModel.setRowState(行号,'disabled',true);
卡片页面设置系统按钮的隐藏
function (event) {
var viewModel = this;
viewModel.on('afterRule',function(event){
viewModel.get('btnBizFlowPush').setVisible(false);
})
}
设置布局(容器)的隐藏
viewmodel.execute('updateViewMeta', { code: 'cGroupCode', visible: false });
列表页面数据取消自动查询
function (event) {
var viewModel = this;
viewModel.getParams().autoLoad = false;
}
多个表格情况下，获取指定表格
function (event) {
var viewModel = this;
//表格的childrenfield属性值
var gridmodel = viewModel.get('childrenfield');
}
切换页签进行数据过滤
function (event) {
var viewModel = this;
var currentTab = "tabpane5mi";
viewModel.on('beforeSearch',function(args){
args.isExtend = true;
var commonVOs = args.params.condition.commonVOs; //通用检查查询条件
var reqValue = currentTab =="tabpane5mi"?"页签1":"页签2";
commonVOs.push({
itemName:'new1',
op:'eq',
value1:reqValue
});
})
viewModel.on('afterTabActiveKeyChange',function(info){
const {key} = info;
if(key=="tabpane5mi"){
//页签1
currentTab = "tabpane5mi";
}else{
//页签2
currentTab = "tabpane9sd";
}
const filtervm = viewModel.getCache('FilterViewModel');
filtervm.get('search').execute('click',{model:viewModel,solutionid:filtervm.getCache('schemeId')});
})
}
列表页面表格行按钮控制显示隐藏
function (event) {
var viewModel = this;
//获取当前的model
let gridModel = viewModel.getGridModel();
//afterSetDataSource界面加载完成后，对数据进行修改
gridModel.on('afterSetDataSource', () => {
//获取列表所有数据
const rows = gridModel.getRows();
//从缓存区获取按钮
const actions = gridModel.getCache('actions');
if (!actions) return;
const actionsStates = [];
rows.forEach(data => {
const actionState = {};
actions.forEach(action => {
//设置按钮可用不可用
actionState[action.cItemName] = { visible: true };
if(action.cItemName == 'btnDelete'){
if(data.enable==1){
actionState[action.cItemName] = { visible: false };
}
}
});
actionsStates.push(actionState);
});
setTimeout(function(){
gridModel.setActionsState(actionsStates);
},50);
});
}
希望组织不受权限控制（特殊场景）
viewModel.get("SalesOrgVO_name").on('beforeBrowse', function (data) {
data.externalData = {
"noPermissionRequired": true
};
});
显示指定枚举值
function (event) {
var viewModel = this;
viewModel.on('afterLoadData',function(){
var data = [{'value':'1','text':'编史修志','nameType':'string'},{'value':'2','text':'工作察考','nameType':'string'},{'value':'3','text':'宣传教育','nameType':'string'}];
viewModel.get('lymd').setDataSource(data);
})
}
卡片界面根据页面状态按钮控制显示
//通过页面规则可以实现，不建议用函数
function (event) {
var viewModel = this;
viewModel.on("modeChange",function (data) {
if(data == "add"){
viewModel.get("button24rj").setVisible(true);
}else{
viewModel.get("button24rj").setVisible(false);
}
});
}
获取卡片页面的单据状态
//通过页面规则可以实现，不建议用函数
var currentState = viewModel.getParams().mode;
联动动态控制组件是否可编辑
//通过页面规则可以实现，不建议用函数
function (event) {
var viewModel = this;
var sexModel=viewModel.get("sex"); //获取ListModel
sexModel.on('afterValueChange',function(data){
if(data.value.value=="1"){
let phoneModel=viewModel.get("phone"); //获取手机控件
phoneModel.setVisible(true);
gridModel.setReadOnly(false); //设置gridModel可编辑
}
}
删除行后处理
//该举例是金额计算，不建议用函数，建议使用页面规则-公式
function (event) {
var viewModel = this;
viewModel.on('afterDeleteRow', function (args) {
var rows = viewModel.getGridModel().getRows();
if(rows.length>0){
var totaldata = 0;
rows.forEach(data => {
if(data.jine==""||data.jine==undefined)data.jine=0;
totaldata+=data.jine;
});
viewModel.get("zongjine").setValue(totaldata);
}
});
}
编辑表格单元格后事件
//该举例是金额计算，不建议用函数，建议使用页面规则-公式
function (event) {
var viewModel = this;
var gridModel = viewModel.getGridModel();
gridModel.on("afterCellValueChange",function(data){
var cellName = data.cellName;
if(cellName=='jine'){
var rows = viewModel.getGridModel().getRows();
if(rows.length>0){
var totaldata = 0;
rows.forEach(data => {
if(data.jine==""||data.jine==undefined)data.jine=0;
totaldata+=data.jine;
});
viewModel.get("zongjine").setValue(totaldata);
}
}
});
}
常用事件函数
//设置时间
var formatDate = function (date){
var y = date.getFullYear();
var m = date.getMonth()+1;
m = m < 10 ? '0' + m : m;
var d = date.getDate();
d = d < 10 ? ('0'+d ) : d;
return y + '-' + m + '-' + d;
};
//设置时间带时分秒
var formatDateTime = function(date){
var y = date.getFullYear();
var m = date.getMonth()+1;
m = m < 10 ? '0' +m : m;
var d = date.getDate();
d = d < 10 ? ('0'+d) : d;
var hh = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();
var mm = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();
var ss = date.getSeconds() < 10 ? "0" + date.getSeonds() : date.getSeconds();
return y + '-' + m + '-' + d + ' ' + hh + ':' + mm + ':' + ss;
};
常用判断字符串是否为空
//判断字符是否为空的方法
function isEmpty(obj){
if(typeof obj == "undefined" || obj == null || obj == ""){
return true;
}else{
return false;
}
}
更改输入框为密码框
function (event) {
var viewModel = this;
viewModel.on('afterMount',function(){
//ID: 页面编码|字段编码
var inputPas = document.getElementById("9978d74e|new1").getElementsByTagName("input")[0];
inputPas.type = 'password';
});
}
设置树结构显示多个字段
//目前支持直接配置，不建议用函数
function (event) {
var viewModel = this;
viewModel.on('afterMount',function(){
var treeModel = viewModel.getTreeModel();
treeModel.setState('titleField',['code','name'])
})
}
