EXT用AJAX传值到后台简单处理

Ext.Ajax.request({
// 发送请求
url : deleteUrl,
method : 'POST',
params : {
jsonStr : Ext.util.JSON.encode(recordIdArr)

}})

public String delDataInPollBean(Model model) {
String ids = model.getValue("jsonStr");
System.out.println(ids);
String reslutStr = ids.replace("[", "(").replace("]", ")")
.replaceAll("\"", "\'");
//   ["1"]——>('1')
System.out.println(reslutStr);
this.runEnvironmentPollService.delDataInPollBean(reslutStr);
return "{success:true}";
}
