html：
<div class="mouse-move fl f12 h22 lh22 mg-r5 sms-item"
@dragstart="dragStart($event, item.labelName)"
draggable='true'
v-for="(item, index) in modelCommonList"

@click="dropRelease($event, item.labelName)">
{{item.labelName}}
</div>
<div contenteditable="true"

</div>
methods：
insertHtmlAtCaret(html) {
let sel, range;
if (window.getSelection) {
// IE9 and non-IE
sel = window.getSelection();
if (sel.getRangeAt && sel.rangeCount) {
range = sel.getRangeAt(0);
range.deleteContents();
let el = document.createElement("div");
el.appendChild(html)
var frag = document.createDocumentFragment(), node, lastNode;
while ((node = el.firstChild)) {
lastNode = frag.appendChild(node);

range.setStartAfter(lastNode);
range.collapse(true);
sel.removeAllRanges();
sel.addRange(range);
}
}
} else if (document.selection && document.selection.type != "Control") {
// IE < 9
document.selection.createRange().pasteHTML(html);
}
},
//开始拖动可选字段
dragStart(event, name) {
event = event || window.event;
this.dragging = name; //str
event.dataTransfer.setData(" ", " "); //for firefox

//阻止默认事件
