ext ajax 乱码问题
1.提交时用 (在 js 中) escape,其转后如 %u33ea (unicode 码)2.在后台在把 unicode 码 转为GBK（下面给出可执行类），如果数据库要用iso-8859-1,再用 new String(str.getByte("gbk"),"iso-8859-1") 转一下
js:
var my_doaddMatrixOutNum = function(){Ext.lib.Ajax.defaultPostHeader += ";charset=utf8";Ext.Ajax.request({// 请求地址url : 'misliveaction.do?method=addMatrixOutNum',// 提交参数组params : {matrixname :escape(Ext.get('matrixname').dom.value) ,outputnum :Ext.get('outputnum').dom.value ,desc:escape(Ext.get('m_desc').dom.value)},// 成功时回调success : function(response, options) {ds.reload();winf.hide();// 获取响应的json字符串var responseArray = Ext.util.JSON.decode(response.responseText);if (responseArray.success == true) {Cookies.set('Allcard_userName', responseArray.user);} else {}}});}
action:
bean.setName(MyString.gbktoIso(MyString.Unicode2GBK(name.replace("%", "\\"))));bean.setUrl_name(outputnum);bean.setDescription(MyString.gbktoIso(MyString.Unicode2GBK(desc.replace("%", "\\"))));dao.addMatrixOutNum(bean);
