前端的小玩意.删除.折叠.最大化.拖拽布局.树状菜…

Array.prototype.indexOf = function (val) {
for (var i = 0; i < this.length; i++) {
if (this[i] == val) return i;
}
return -1;
};
Array.prototype.remove = function (val) {
var index = this.indexOf(val);
if (index > -1) {
this.splice(index, 1);
}
};

function Delete(obj) {
var m = document.getElementById(obj);

m.parentNode.removeChild(m);

}

<a class="btn btn-default pull-right" onclick="Delete('wid-id-2')">
<span class="glyphicon glyphicon-remove"></span>
</a>

<a class="btn btn-default pull-right" data-toggle="collapse" href="#realtime">
<span class="fa fa-expand"></span>
</a>

 href="#realtime" 就是要折叠的div

function ChangeVehicleCharts() {
var mycars = ["wid-id-0", "wid-id-1", "wid-id-2"];
for (var i = 0; i < mycars.length; i++) {
if ("wid-id-1" == mycars[i]) {

mycars.remove(mycars[i]);
}
}
for (var i = 0; i < mycars.length; i++) {
var item = document.getElementById(mycars[i]);
if (item != null) {
item.parentNode.removeChild(item);
}
}
document.getElementById("VehicleCharts").style.height = $(window).height() * 0.8 + "px";
document.getElementById("VehicleCharts").style.width = $(window).width() * 0.8 + "px";
myChart = echarts.init(document.getElementById('VehicleCharts'));
myChart.setOption(option);
myChart.resize();
}

<div class="jarviswidget" id="wid-id-0" data-widget-togglebutton="false" data-widget-editbutton="false" data-widget-fullscreenbutton="false" data-widget-colorbutton="false" data-widget-deletebutton="false">

  <div id="tree"></div>

      $('#tree').treeview({ data: data, showCheckbox: true });
