关于在extjs中使用column布局，不能显示textfield的标签（fieldLabel）解决方法

摘自：http://blog.csdn.net/suixufeng/article/details/6587989

原因：fieldLabel is not rendered by the field itself, but by FormLayout. So for you to have a label you need to put the field in a form layout, e.g.

在coluumn的子项中加上layout:'form'就ok了

 

错误示例：

[php] view
plain copy

var d = new Ext.Window({   

        title: instance,   

        layout: 'border',   

        width:375,   

        height:275,   

        cls: 'x-dialog-popup-main',   

        items: [{   

            region: 'center',   

            title: 'General Information',   

            layout: 'table',   

            layoutConfig: { columns: 2 },   

            items: [   

                new Ext.form.TextField({   

                    colspan: 2,   

                    fieldLabel: 'My Label',   

                    disabled: true,   

                    hideLabel: false   

                })   

            ]   

        }, {   

            region: 'south',   

            title: 'Controls',   

            height: 100   

        }]   

    });    

需改动的：

[php] view
plain copy

layout: 'table',  

layoutConfig: {columns: 2},  

items: [{  

  layout: 'form',  

  colspan: 2,   

  items: [{  

    xtype: 'textfield'  

    fieldLabel: 'My Label',   

    disabled: true,  

  }]  

}]
