前台 html：
<ul class="easyui-tree" id="ul_Tree" data-options="fit:true,animate:true"></ul>
javascript 加载
$("#ul_Tree").tree({
url: ‘/webservice/CreditExtension/CreditExtension.asmx/QueryImages?Hid_FileCode=‘ + $("#Hid_FileCode").val() + "&imgstyle=0&r=" + new Date().getMilliseconds(),
method: ‘get‘,
onSelect: function (note) {
if (note.attributes != undefined && note.attributes != "") {
var style = note.attributes.substr(note.attributes.lastIndexOf("."), note.attributes.length - note.attributes.lastIndexOf("."));
if (style == ".bmp" || style == ".gif" || style == ".jpg" || style == ".png" || style == ".jpeg") {
setTheFirst(note.attributes);
$("#img_show").attr("src", note.attributes);
$("#div_title").html(note.text);
} else { window.open(note.attributes, "preview", ""); }
}
else { $("#ul_Tree").tree("toggle", note.target); }
}
});
后台返回json：
public string GetToTreeJson(DataSet ds)
{
StringBuilder result = new StringBuilder();
result.Append("[");
foreach (DataRow dr in ds.Tables[0].Rows)
{
result.Append("{\"id\":0,\"text\":\"" + dr["text"].ToString() + "\",\"iconCls\":\"icon-hkb\"");
DataRow[] drs = ds.Tables[1].Select(" parent_id=‘" + dr["id"].ToString() + "‘");
if (drs.Length > 0)
{
result.Append(",\"state\":\"closed\",\"children\":[");
for (int i = 0; i < drs.Length; i++)
{
if (i > 0) result.Append(",");
result.Append("{\"id\":" + drs[i]["id"].ToString() + ",\"text\":\"" + drs[i]["text"].ToString() + "\",\"attributes\":\"" + imgpath + formatString(drs[i]["attributes"].ToString()) + "\",\"iconCls\":\"icon-" + getStyle(drs[i]["attributes"]) + "\"}");
}
result.Append("]");
}
else
{
result.Append(",\"state\":\"open\"");
}
result.Append("},");
}
result.Remove(result.Length - 1, 1);
result.Append("]");
return result.toString();
}
