Bootstrap 3 Placing Icon inside input field

问题

I am working in Bootstrap 3 and am trying to get a calendar icon inside the right hand side of the input box.

My html looks like this:

<div class="col-md-12">
    <div class='right-inner-addon col-md-2 date datepicker' 
         data-date-format="yyyy-mm-dd">
        <input name='name' value="" type="text" class="form-control date-picker"
               data-date-format="yyyy-mm-dd"/>
        <i class="fa fa-calendar"></i>
    </div>
</div>

I have tried position: absolute like this:

.right-inner-addon i {
    position: absolute;
    right: 5px;
    top: 10px;
    pointer-events: none;
    font-size: 1.5em;
}
.right-inner-addon {
    position: relative;
}

But when I do it will look great in one spot, but will not be positioned correctly in another instance.

I have also tried to see if I could use text-indent to see if this would work throughout, but it had the same effect.

.right-inner-addon i, 
.form-group .right-inner-addon i {
    display: inline-block;
    z-index: 3;
    text-indent: -15px;
    font-size: 1.3em;
}

Here's a jsFiddle that might help

You can use input-group add-on with a input-group-btn.

<div class="col-md-12">
    <div class='input-group add-on col-md-2 date datepicker' 
         data-date-format="yyyy-mm-dd">
        <input name='name' value="" type="text" class="form-control date-picker" 
               data-date-format="yyyy-mm-dd"/>
        <div class="input-group-btn">
            <button class="btn btn-default">
                <i class="fa fa-calendar"></i>
            </button>
        </div>
    </div>
</div>

With a little CSS to hide the button border:

/* remove border between controls */
.add-on .input-group-btn > .btn {
    border-left-width: 0;
    left:-2px;
    -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
            box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
}
/* stop the glowing blue shadow */
.add-on .form-control:focus {
    -webkit-box-shadow: none; 
            box-shadow: none;
    border-color:#cccccc; 
}

Using bootstrap's native validation states is probably preferable to writing custom CSS here.
^{And I'm pretty sure that I'm the one who came up with the CSS in question.}

Just use .has-feedback on your form-group and .form-control-feedback on your icon:

<div class="form-group has-feedback">
    <label class="control-label sr-only">DatePicker</label>
    <input type="text" class="form-control date-picker" /> 
    <i class="fa fa-calendar form-control-feedback"></i>
</div>

Check this fiddle, adapted from this answer

The difference being that in your case the <i> was placed after <input>. Swapping them makes it work. That's why the positioning was creating a mess as opposed to the cited answer.

In above answers, Input click works but click on i tag is not working. so I have added my code in answer of @KyleMit

<div class="form-group has-feedback">
  <input type="text" name="txtDatepicker" class="form-control date-picker" /> 
  <i class="glyphicon glyphicon-calendar" 
    onclick="javascript:$('input[name=txtDatepicker]').data('DateTimePicker').show();">
  </i>
</div>

I changed css little bit for my UI. You also can change it.

<style>
  .right-inner-addon {
    position: relative;
   }

    .right-inner-addon input {
        padding-right: 30px;
    }

    .right-inner-addon i {
        position: absolute;
        left: 256px;
        padding: 14px 12px;
    }
</style>
