问题1、$.fn.zTree为空或为Undefined
我在MVC中引用Jquery插件Ztree的JS并不存任何问题，而当我将Ztree的js引入项目中，就出现$.fn.zTree为空或为Undefined问题，网上搜索一番并没有什么针对性的意见和建议，不过看到说是JS的引用顺序出现问题。只需将jquery.ztree.all-3.0.js的js 放在最后就可以。
问题2、Jquery版本高于1.9.1就出现$.browser.msie不存此属性
(function (jQuery) {

if (jQuery.browser) return;

jQuery.browser = {};
jQuery.browser.mozilla = false;
jQuery.browser.webkit = false;
jQuery.browser.opera = false;
jQuery.browser.msie = false;

var nAgt = navigator.userAgent;
jQuery.browser.name = navigator.appName;
jQuery.browser.fullVersion = '' + parseFloat(navigator.appVersion);
jQuery.browser.majorVersion = parseInt(navigator.appVersion, 10);
var nameOffset, verOffset, ix;

// In Opera, the true version is after "Opera" or after "Version" 
if ((verOffset = nAgt.indexOf("Opera")) != -1) {
    jQuery.browser.opera = true;
    jQuery.browser.name = "Opera";
    jQuery.browser.fullVersion = nAgt.substring(verOffset + 6);
    if ((verOffset = nAgt.indexOf("Version")) != -1)
        jQuery.browser.fullVersion = nAgt.substring(verOffset + 8);
}
// In MSIE, the true version is after "MSIE" in userAgent 
else if ((verOffset = nAgt.indexOf("MSIE")) != -1) {
    jQuery.browser.msie = true;
    jQuery.browser.name = "Microsoft Internet Explorer";
    jQuery.browser.fullVersion = nAgt.substring(verOffset + 5);
}
// In Chrome, the true version is after "Chrome" 
else if ((verOffset = nAgt.indexOf("Chrome")) != -1) {
    jQuery.browser.webkit = true;
    jQuery.browser.name = "Chrome";
    jQuery.browser.fullVersion = nAgt.substring(verOffset + 7);
}
// In Safari, the true version is after "Safari" or after "Version" 
else if ((verOffset = nAgt.indexOf("Safari")) != -1) {
    jQuery.browser.webkit = true;
    jQuery.browser.name = "Safari";
    jQuery.browser.fullVersion = nAgt.substring(verOffset + 7);
    if ((verOffset = nAgt.indexOf("Version")) != -1)
        jQuery.browser.fullVersion = nAgt.substring(verOffset + 8);
}
// In Firefox, the true version is after "Firefox" 
else if ((verOffset = nAgt.indexOf("Firefox")) != -1) {
    jQuery.browser.mozilla = true;
    jQuery.browser.name = "Firefox";
    jQuery.browser.fullVersion = nAgt.substring(verOffset + 8);
}
// In most other browsers, "name/version" is at the end of userAgent 
else if ((nameOffset = nAgt.lastIndexOf(' ') + 1) <

(verOffset = nAgt.lastIndexOf('/'))) {
jQuery.browser.name = nAgt.substring(nameOffset, verOffset);
jQuery.browser.fullVersion = nAgt.substring(verOffset + 1);
if (jQuery.browser.name.toLowerCase() == jQuery.browser.name.toUpperCase()) {
jQuery.browser.name = navigator.appName;
}
}
// trim the fullVersion string at semicolon/space if present
if ((ix = jQuery.browser.fullVersion.indexOf(";")) != -1)
jQuery.browser.fullVersion = jQuery.browser.fullVersion.substring(0, ix);
if ((ix = jQuery.browser.fullVersion.indexOf(" ")) != -1)
jQuery.browser.fullVersion = jQuery.browser.fullVersion.substring(0, ix);

jQuery.browser.majorVersion = parseInt('' + jQuery.browser.fullVersion, 10);
if (isNaN(jQuery.browser.majorVersion)) {
    jQuery.browser.fullVersion = '' + parseFloat(navigator.appVersion);
    jQuery.browser.majorVersion = parseInt(navigator.appVersion, 10);
}
jQuery.browser.version = jQuery.browser.majorVersion;

})(jQuery);
在JS上加上以上代码即可。
问题3、修改Ztree数据源的标示字段
{ id:1, pId:0, name:"随意勾选 1", open:true},
{ id:11, pId:1, name:"随意勾选 1-1"},
{ id:12, pId:1, name:"随意勾选 1-2", open:true},
{ id:121, pId:12, name:"随意勾选 1-2-1"},
{ id:122, pId:12, name:"随意勾选 1-2-2"},
{ id:2, pId:0, name:"禁止勾选 2", open:true, doCheck:false},
{ id:21, pId:2, name:"禁止勾选 2-1", doCheck:false},
{ id:22, pId:2, name:"禁止勾选 2-2", checked:true, open:true, doCheck:false},
{ id:221, pId:22, name:"禁止勾选 2-2-1", doCheck:false},
{ id:222, pId:22, name:"禁止勾选 2-2-2", checked:true, doCheck:false},
{ id:23, pId:2, name:"禁止勾选 2-3", doCheck:false}
id、pId、name、checked、open等这些字段均可以修改，但需要将Js中对应的读取字段修改掉
