Idea小技巧 之 折叠代码块(默认折叠所有ctrl+shift+/,展开所有ctrl+*)

(可以直接在类上右键点击,选择Folding)具体详解:https://blog.csdn.net/wxxmy/article/details/78308079

防止复选框的默认操作：

document.getElementById("myCheckbox").addEventListener("click", function(event){
  event.preventDefault()
});

工作中常用正则记录，只能输入英文，数字，下划线等等

angular树状图刷新(只刷新树状图)

// 外部更新
function updateTreeView(item, type) {
    var angularElement = $("[ng-controller='orgManager.ctrl']");
    var scope = angular.element(angularElement).scope();
    scope.updateTreeView(item, type);
    //关键在这
    scope.treeData.read();
}

 $scope.treeData = new kendo.data.HierarchicalDataSource({
        transport: {
            read: {
                type: "get",
                url: DSJS.getWebRoot() + "/org/get_childrenorgs_asyn_all",
                dataType: "json",
                contentType: "application/json"
            }
        },
        schema: {
            model: {
                hasChildren: "items"
            },
            data: function (res) {
                if (res && res.ret == "ok") {
                    return res.dataStore;
                } else {
                    return [];
                }
            }
        },
        //加载完成后执行
        requestEnd: function (e) {
        }
    });

AngularJS在某些情况下,不能直接用required+data-required-msg=" "的方式,直接控制必填文字提示的显示,比如input为下拉框的时候,此时就需要通过利用id操作标签的display属性控制标签的显示或者隐藏

实例:
html

<div class="col-xs-6 ds-form">
                <div class="org org1">
                    <label class="col-xs-3 org_child required">{{"COMMON.LABEL.RESPONSIBLE.DEPT"|translate}}</label>
                    <div class="col-xs-9 org_child">
                        <div class="col-xs-12" style="position: absolute;top:-25px;padding-left:0px;display: none" title={{dutyOrg}} ng-show="showDutyOrg">
                            <p style="color:#dbdbdb;overflow-x:hidden;text-overflow: ellipsis;white-space: nowrap;">{{dutyOrg}}</p>
                        </div>
                        <div style="padding: 0px;" id="unitNameDutyOrgId" ds-combo-tree="unitNameDutyOrg" ds-model="dataStore.data.orgNodeId" ds-model-text="dataStore.data.orgName" ds-data-source="defUnitTreeDataDutyOrg" ds-data-value-field="'id'" ds-data-text-field="'text'"
                             ds-value-primitive="true" ds-auto-close="true" ds-on-select="dutyOrgSelect(dsEvent)" ng-disabled="disabled" required  validationMessage={{"PERSON.SELECT.ORG"|translate}}>
                        </div>
<!--                        <span ng-show="showDutyOrgError" class="k-widget k-tooltip k-tooltip-validation k-invalid-msg" data-for={{"RESOURCE.LABEL.RESPONSIBLE.DEPT"|translate}} style="z-index:-999;margin-top: 2px;">-->
                        <span id="showDutyOrgWarn" class="k-widget k-tooltip k-tooltip-validation k-invalid-msg"  ng-hide=false data-for={{"COMMON.LABEL.RESPONSIBLE.DEPT"|translate}} style="z-index:-999;margin-top: 2px;">
                            <span class="k-icon k-i-warning" style="margin-top: 2px;"></span>{{"COMMON.VALIDATION.REQUIRED"|translate}}
                        </span>
                    </div>
                </div>

JS

	//设定行政区域所在单位非空提示不可见
   $("#showDutyOrgWarn").css("display", "none");
   if ($scope.dataStore.data.orgNodeId == null || $scope.dataStore.data.orgNodeId == "") {
               // $scope.showDutyOrgError = true;
               $("#showDutyOrgWarn").css("display", "block").css("visibility", "visible");
               return false;
           }
