textArea异步获取数据换行

前台:

this.train_result = new Ext.form.TextArea

({

xtype : 'textarea',

anchor : '95%',

id : Ext.id(),

name : 'train_result',

grow : true,

growMax : 150,

growMin : 50,

fieldLabel : '培训收获'

});

Ext.Ajax.request

({

url: '../trainComment/get_train_result',

success: function(response, options)

{

var result = Ext.util.JSON.decode(response.responseText);

this.train_result.setValue(result.train_result);

},

failure: function(response, options)

{

this.train_result.setValue(0);

},

scope : this,

params: { id : this.uid }

});

后台追加的换行：

result += it.train_other + "//n"
