javascript實作TreeView 無刷新展開的實例程式碼_javascript技巧

複製程式碼 程式碼如下:

function public_GetParentByTagName(element, tagName) 
{
    var parent = element.parentNode;  要的tag繼續上溯
    while (parent && (parent.tagName.toUpperCase() != upperTagName)) 
    {
  }
    return parent;
}
//設定節點的父節點Cheched－該節點可訪問，則他的父節點也必能存取
function setParentChecked(objNode)
{
    var objParentDiv = public_GetParentByTagName(objNode,"div");
    if(objParentDiv==null || objParentDiv== "undefined") 🎜>    }
    var objID = objParentDiv.getAttribute("ID");
    objID = objID.substring(0,objID.indexOf("Nodes"));
  遠 | getElementById(objID);
    if(objParentCheckBox==null || objParentCheckBox == "undefined")
    {
 entCheckBox.tagName!="INPUT" && objParentCheckBox.type == "checkbox")
    return; 
    objParentCheckBox.checked = true;
    setParentChecked(objParCheckBox);不可訪問，則他的子節點也不能訪問
function setChildUnChecked(divID)
{ 
    var objchild = divID.children;
 =0;i    {
        var tempObj = objchild[i];
  🎜>        {
            tempObj.checked = false;
   🎜>    }
}
//設定節點的子節點cheched－此節點可以訪問，則他的子節點也都能存取
function setChildChecked(divID)
{ 
    var objchild = divID.children;
   ;i    {
        var tempObj = objchild[i];
   {
            tempObj.checked = true;
        }
   >//觸發事件
function CheckEvent()
{
    var objNode = event.srcElement; 
    if(objNode.tagName!="INPUT" || objNode.type!="checkbox")
  🎜>    {
        setParentChecked(objNode);
        var objID = objNode.getAttribute( (0,objID.indexOf("CheckBox")); 
        var objParentDiv = document.getElementById(objID "Nodes");
        if(objParentTiv==null || objPar    if(objParentDiv==null || objPar            return;
        } 
        setChildChecked( objParentDiv);
    }
else
{
var objID = objNode.getAttribute("ID");
var objID = objID.substring(0,objID.indexOf("CheckBox"));
var objParentDiv = document.getElementById(objID "Nodes");
        if(objParentDiv==null || objParentDiv == "undefined")                                                 UnChecked(objParentDiv);
}
}


Server control

Copy code

The code is as follows:this.tvPrivilege.Attributes.Add("OnClick", "CheckEvent()");
