<h1>File Upload Field</h1>
|
|
<p>This example demonstrates use of Ext.form.field.File, a file upload field with custom rendering.</p>
|
<p>The js is not minified so it is readable. See <a href="file-upload.js">file-upload.js</a>.</p>
|
|
<h2>Basic File Field</h2>
|
<p>
|
A typical file upload field with Ext style. Direct editing of the text field cannot be done in a consistent,
|
<br>
|
cross-browser way, so it is always read-only. The file path reported by the <code>getValue</code> method will
|
</p>
|
<div id="fi-basic"></div>
|
<div id="fi-basic-btn"></div>
|
|
<h2>Button Only</h2>
|
<p>
|
You can also render the file input as a button without the text field, with access to the field's value via the
|
<br>
|
standard <tt>Ext.form.field.Field</tt> interface or by handling the <tt>fileselected</tt> event (as in this example).
|
</p>
|
<div id="fi-button"></div>
|
<div id="fi-button-msg" style="display:none;"></div>
|
<div class="x-clear"></div>
|
|
<h2>Form Example</h2>
|
<p>
|
The File field can also be used in form layouts just like any other field, with support for labeling,
|
<br>
|
validation (the field is required in this example), empty text, etc. This example also demonstrates
|
<br>
|
using the <tt>buttonConfig</tt> option to provide a customized icon upload button.
|
</p>
|
<div id="fi-form"></div>
|
|
<h2>Form Example with failure returned from server</h2>
|
<p>
|
This is the same as the form above, except that the server simulates an upload error and returns a failure JSON packet.
|
<br>
|
Explanatory messages are returned in the data packet and processed by the UI.
|
<br>
|
You may set the HTTP response status which the server responds with. It is recommended that applications
|
return a 200, <code><b>success</b></code> response when returning failure packets. The <b>HTTP</b> request
|
is successful. The error is an application-level failure.
