在收到 AJAX 请求的响应后,我无法重新加载 dynatree。我在下面的代码中有一个下拉“plan.viewType”。我在此下拉列表中选择的新值上调用 JS 函数,该值又将调用 AJAX 函数。
<form:select path="plan.viewType" id="viewType" style="width:11.6em" onChange="loadView()" multiple="false">
<form:options items="${plan.viewType}"/>
</form:select>
我有两棵树——dim_tree 和 kpi_tree。
$(document).ready(function(){
$.fn.clearable = function (treeid) {
var $this = this;
$this.wrap('<div class="clear-holder" />');
var helper = $('<span class="clear-helper">x</span>');
$this.parent().append(helper);
helper.click(function(){
$this.val("");
$('#' + treeid).dynatree('getRoot').search("");
});
};
$("#dimsearch").clearable("dim_tree");
$("#kpisearch").clearable("kpi_tree");
$("#dim_tree").dynatree({
checkbox: true,
selectMode: 3,
children: (isEdit == "true")? eval('('+'${plan_dimension_edit_info}'+')') : eval('('+'${plan_dimension_info}'+')'),
dnd: {
onDragStart: function (node) {
return false;
},
onDragStop: function (node) {
return false;
},
onDragOver: function (targetNode, sourceNode, hitMode) {
return false;
},
onDrop: function (targetNode, sourceNode, hitMode, ui, draggable) {
return false;
}
},
onSelect: function(select, node) {
if(select && dimKPIMisMatch(node)) {
node.select(false);
//showToolTip(node.span, dimMsg);
return;
}
createTreeSortable(select, node, "DIM");
}
});
$("#kpi_tree").dynatree({
checkbox: true,
selectMode: 3,
children: (isEdit == "true")? eval('('+'${plan_measurement_edit_info}'+')') : eval('('+'${plan_measurement_info}'+')'),
dnd: {
onDragStart: function (node) {
return false;
},
onDragStop: function (node) {
return false;
},
onDragOver: function (targetNode, sourceNode, hitMode) {
return false;
},
onDrop: function (targetNode, sourceNode, hitMode, ui, draggable) {
return false;
}
},
onSelect: function(select, node) {
if(select && kpiDIMMisMatch(node)) {
node.select(false);
//showToolTip(node.span, kpiMsg);
return;
}
createTreeSortable(select, node, "KPI");
}
});
});
当我从下面的 AJAX 调用中得到响应时,我想重新加载这两个树。
var loadView = function() {
if($("#viewType").val() == "Default View") {
$.ajax({
url : "planmntsdefault.do",
type : "GET",
success : function (data) {
var node = $("#dim_tree").dynatree("getTree").getRoot();
if(node && node.isLazy())
{
node.reloadChildren(function(node, isOk){
if(!isOk) alert("Node " + node + " could not be reloaded.");
else alert("Tree reloaded");
});
}
else
{
node.activate();
node.reloadChildren(function(node, isOk){
if(!isOk) alert("Node " + node + " could not be reloaded.");
else alert("Tree reloaded");
});
}
node = $("#kpi_tree").dynatree("getTree").getRoot();
if(node && node.isLazy())
{
node.reloadChildren(function(node, isOk){
if(!isOk) alert("Node " + node + " could not be reloaded.");
else alert("Tree reloaded");
});
}
else
{
node.activate();
node.reloadChildren(function(node, isOk){
if(!isOk) alert("Node " + node + " could not be reloaded.");
else alert("Tree reloaded");
});
}
},
error : function ( xhr, textStatus, error ) {
}
});
}
}
我提到了其他帖子如何重新加载/刷新/重新初始化 DynaTree?这并没有解决问题。我尝试了另一种变体,我确实破坏并重新加载。这些方法都不起作用。我在这里错过了什么吗?谢谢。
