Tips for properly positioning the ko validation message in case it is lengthy

I have implemented ko validation messages in order to validate input fields. Can anyone provide guidance on how to align the validation message correctly within the specified location?

<input id="personName" class="form-control placeholder has-error" type="text"
 data-bind="value: name" style="width:225px;">
ko.validation.init({insertMessages: true});
var vm = {
    name: ko.observable('name').extend({required: { message: "Please enter a username.", params: true }, email: { message: "Username should be in a valid email address format which is used.", params: true }})
}
ko.applyBindings(vm);

For reference, my code can be found at http://jsfiddle.net/Td7zZ/2/

Answer №1

To modify your DOM layout, you can create a fixed-width container and float the input and dynamically generated JS span elements to the left with specific widths. Alternatively, you can float them to both the left and right.

View Demo 3 Multiple input elements nested under ul and li with self-clearing li


div {
    width: 500px;
    border: 1px solid #f00;
    overflow: hidden;
}

.form-control, .form-control + span {
    float: left;
}

.form-control {
    width: 200px;
}

.form-control + span {
    width: 270px;
}

Note: For multiple input fields, use ul and li elements and remember to clear the float after each li.

Answer №2

To style your input, apply the following CSS code:

input, .form-control {
    float: left;
    margin: 0 5px 0 0;
    width: 225px;
}

Answer №3

To ensure that the CSS is applied to all tags, it's necessary to bind it to a div. This can be achieved with code like the following:

<div data-bind="attr: { class: 'wrap'}" > 

  <input id="personName" class="form-control placeholder has-error" type="text" 
    data-bind="  value: name " style="width:225px;"  />

</div>

Below is the accompanying CSS:

  .wrap {
    width:500px;
    display:inline-block;
    border:1px solid blue;
  }
