修改xloadtree 支持checkbox radio 鼠标右键菜单
结合JSON 支持动态从数据库加载节点，支持鼠标右键菜单，支持checkbox 和radio
把数据加载的节点信息保存在下面的类中：
public class Node {
private String text;
private String action;
private String src;
private String icon;
private String openIcon;
private String target;
private int checkboxType;
private boolean isChecked;
private String value;
private String oncontextmenu;
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public String getAction() {
return action;
}
public void setAction(String action) {
this.action = action;
}
public String getSrc() {
return src;
}
public void setSrc(String src) {
this.src = src;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public String getOpenIcon() {
return openIcon;
}
public void setOpenIcon(String openIcon) {
this.openIcon = openIcon;
}
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
public int getCheckboxType() {
return checkboxType;
}
public void setCheckboxType(int checkboxType) {
this.checkboxType = checkboxType;
}
public boolean getIsChecked() {
return isChecked;
}
public void setIsChecked(boolean isChecked) {
this.isChecked = isChecked;
}
public String getOncontextmenu() {
return oncontextmenu;
}
public void setOncontextmenu(String oncontextmenu) {
this.oncontextmenu = oncontextmenu;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
src ：加载数据库数据URL
action：点击节点上的文字要执行的javascritp事件
text：节点上显示的文字
checkboxType：1=checkbox,2=radio
value : checkbox,radio的值
其他参数根据名字和代码自己研究去例子view.jsp
