ExtJs依赖字段验证 [英] ExtJs dependent field validation

问题描述

如何验证一个取决于另一个字段的字段？

How do I validate one field which is dependent on another field?

{
  xtype:          'textfield',
  name:           'name2',
  vtype:          'type',      // how to write the validation code for this if it 
                               // depends on the value of another field?
  allowBlank:     false
}

推荐答案

添加您自己的自定义验证器，并在其中执行验证。

By adding your own custom validator and therein perform your validation.

var field_one = new Ext.form.TextField({
    name: 'field_one',
    fieldLabel: 'Field one'
});

var field_two = new Ext.form.TextField({
    name: 'field_two',
    fieldLabel: 'Field two',
    validator: function(value){
        if(field_one.getValue() != value) {
            return 'Error! Value not identical to field one';
        } else {
            return true;
        }
    }
});
