zTree节点文字过多的处理方法

zTree setting.view.addDiyDom 方法可以实现自定义控件，指定节点显示内容。因此需要自己实现addDiyDom方法。

如果树节点不显示checkbox ，处理方法为：

function addDiyDom(treeId, treeNode) {
 var spaceWidth = 5;
 var switchObj = $("#" + treeNode.tId + "_switch"),
 icoObj = $("#" + treeNode.tId + "_ico");
 switchObj.remove();
 icoObj.parent().before(switchObj);
 var spantxt = $("#" + treeNode.tId + "_span").html();
 if (spantxt.length > 19) {
 spantxt = spantxt.substring(0, 29) + "...";
 $("#" + treeNode.tId + "_span").html(spantxt);
 }
}

如果树节点有checkbox，处理方法为：

function addDiyDomWithCheck(treeId, treeNode) {
 var spaceWidth = 5;
 var switchObj = $("#" + treeNode.tId + "_switch"),
 checkObj = $("#" + treeNode.tId + "_check"),
 icoObj = $("#" + treeNode.tId + "_ico");
 switchObj.remove();
 checkObj.remove();
 icoObj.parent().before(switchObj);
 icoObj.parent().before(checkObj);

 var spantxt = $("#" + treeNode.tId + "_span").html();
 $("#" + treeNode.tId + "_span").css({"fontSize":13});
 $("#" + treeNode.tId + "_span").attr("data-toggle","tooltip");
 $("#" + treeNode.tId + "_span").attr("data-placement","top");
 if (spantxt.length > 19) {
 spantxt = spantxt.substring(0, 19) + "...";
 $("#" + treeNode.tId + "_span").html(spantxt);
 }

}

zTree view 相关定义如下：

 //树属性的定义 
 var setting = { 
 //页面上的显示效果 
 view: { 
 addHoverDom: addHoverDom, //当鼠标移动到节点上时，显示用户自定义控件 
 removeHoverDom: removeHoverDom, //离开节点时的操作 
 selectedMulti: false,
 txtSelectedEnable: true,
 showLine: true,
 addDiyDom: addDiyDomWithCheck
 }
}

实现效果如下，超长部分将显示为省略号...
