Step by Step validation configuration

The following steps are used to configure validation in In-place Editor.

Step 1: To perform default validation in In-place Editor the name property is mandatory. And the specified name must be the same as the key name.

Step 2: The corresponding name specified in the name property should bind with the validationRules property. For example, in the below code snippet, the Number in the name property is bind with the maxLength of validationRules. Likewise, you can bind with the in-build validation configurations in the above table.

ej.base.enableRipple(true);

var editObj = new ej.inplaceeditor.InPlaceEditor({
  mode: "Inline",
  type: "Numeric",
  name: "Number",
  model: {
    placeholder: "Select Number"
  },
  validationRules: {
    Number: { maxLength: 5 }
  }
});
editObj.appendTo("#numeric");

    </div>

if(ele) {
  ele.style.visibility = "visible";
}   
      </script>

In the following sample, first editor value submitted without select any date, so the default error message will be displayed below the DatePicker element. Second editor configured with the validating event with the handler. In handler event errorMessage argument value modified and it will show below the DatePicker element.

ej.base.enableRipple(true);

//Initialize In-place Editor control
var textObj = new ej.inplaceeditor.InPlaceEditor({
    mode: 'Inline',
    type: 'Date',
    name: 'Today',
    emptyText: 'dd/mm/yyyy',
    model: {
        placeholder: 'Select date'
    },
    validationRules : {
        Today: { required: true }
    }
});

//Render initialized In-place Editor control
textObj.appendTo('#textBox');

//Initialize In-place Editor control
var dateObj = new ej.inplaceeditor.InPlaceEditor({
    mode: 'Inline',
    type: 'Date',
    name: 'Today',
    emptyText: 'dd/mm/yyyy',
    model: {
        placeholder: 'Select date'
    },
    validationRules : {
        Today: { required: true }
    },
    validating: function(e) {
        e.errorMessage = 'Field should not be empty';
    }
});

//Render initialized In-place Editor control
dateObj.appendTo('#date');
