ExtPB.Net中客户端 TreeView 控件功能扩展（1）

   利用extpb.net进行开发，免不了需要自己扩展js的功能，所以我们将一些常见功能进行封装，然后在OpenSheet.aspx.cs中统一加载：

    //注册需要的公共js文件
    this.ClientScript.RegisterClientScriptInclude("MyCommon", "/ExtPB.Net/MyCommon.js")

 

以下是对客户端的TreeView 控件进行扩展的一个方法--查找节点项

 

if (typeof (FINDNODETYPE) == "undefined") {
    var FINDNODETYPE = {
        Data: 0,
        Label: 1
    }
}
if (typeof (MATCHINGTYPE) == "undefined") {
    var MATCHINGTYPE = {
        Exact: 0,
        Vague: 1
    }
}

 

//#region Ex_FindNode - 查找节点项
TreeView.prototype.Ex_FindItem = function (handle, findNodeType, findContent, matchingType) {
    var tvItem = new TreeViewItem();
    var l_found_handle = 0;
    var l_child_handle = 0;
    while (handle != -1) {
        this.GetItem(handle, tvItem);
        var id = tvItem.GetData().toString();
        var label = tvItem.GetLabel();
        if (findNodeType == FINDNODETYPE.Data)
            var value = id;             //按节点Data域查找
        else var value = label;         //按节点Label域查找
        if (matchingType == MATCHINGTYPE.Exact) {   //精确匹配
            if (value == findContent) {
                return handle;
            }
        }
        else {   //模糊匹配（对字符型数据，未做检查）
            if (value.indexOf(findContent) >= 0) {
                return handle;
            }
        }
        ////上面不检查多项
        //判断 handle 项是否有子项,有，则递归调用
        if (tvItem.GetChildren()) {  //有子项
            l_child_handle = this.FindItem(TREENAVIGATION.ChildTreeItem, handle);
            if (l_child_handle > 0) {
                l_found_handle = this.Ex_FindItem(l_child_handle, findNodeType, findContent, matchingType);
            }
        }
        if (l_found_handle > 0) return l_found_handle;
        handle = this.FindItem(TREENAVIGATION.NextTreeItem, handle);
    }
    return -1;
}
//#endregion
