---------------------------------------------前台：
$(document).ready(function() {
var data= [];
$.ajax({
type : 'post',
url : 'orginfo.do?action=getName',
cache : false,
processData : true,
dataType : 'json',
success : function(data) {
alert(data);
},
async: false
});
});
---------------------------------------------后台：
else if ("getName".equals(action)) {
List<?> TableList=orgTableDAO.getName();
List<CheckBoxTree> treeList = getNameList(TableList);
String aa=null;
StringBuffer sb = new StringBuffer();
sb.append("[");
for (int i = 0; i < TableList.size(); i++) {
if (i != 0) {
sb.append(",");
}
aa=treeList.get(i).toJSONStringName();
aa=aa.replace("'", """);
sb.append(aa);
}
sb.append("]");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0L);
response.setContentType("text/html; charset=GBK");
response.getWriter().write(sb.toString());
response.getWriter().close();
-------------------定义为-- dataType : 'json' 就是object
var jsonData=eval("("+data+")");
for(var i=0;i<jsonData.length;i++){
var name = jsonData[i].name;
}
--------------------------------定义为dataType : 'text'
