<h1>Methods for Navigation</h1>

<h2>Forms</h2>
<p class="flow-text">
When you use the <span class = "hlt">form</span> parameter in the <span class = "hlt2">find</span> command and the searched form is found,
digger goes into the form context. In this context, you can fill out the form fields with data, submit forms to the server,
and simulate clicks on the form buttons.
</p>
<p class="flow-text">
The following commands are supported in the form context:
</p>
<table class="responsive-table highlight">
<thead>
<tr>
<th data-field="parameter">Command</th>
<th data-field="description">Description</th>
</tr>
</thead>
<tbody>
<tr>
<td class="centered">fields_set</td>
<td>The command sets the form fields using the specified values. Fields must be referenced through
their names, in other words through the value specified in the <span class = "hlt">name</span> attribute of the field tag.
</td>
</tr>
<tr>
<td>submit</td>
<td>This command submits form to the server.</td>
</tr>
<tr>
<td>click</td>
<td>The command do click the button, defined by name or <span class="hlt">id</span>, provided as parameter for this command.</td>
</tr>
</tbody>
</table>
<p class="flow-text">
As example lets use the following HTML source:
</p>
<pre class="language-markup">
<code class="language-markup"><form name="form1" method="POST">
<input type="text" name="textfield" value="5">
<input type="checkbox" name="checkbox" value="yes">
<select name="select1" >
<option value="yes">yes</option>
<option value="no">no</option>
</select>
<input type="submit" value="send">
<button name="submitbutton" type="submit">send</button>
</form>
</code></pre>
<p class="flow-text">
Here is how we could work with such form:
</p>
<div class="row">
<div class="col s12">
<ul class="tabs excdark">
<li class="tab col s6"><a class="active" href="#form_simple_submit">Simple submission</a></li>
<li class="tab col s6"><a href="#form_field_set">Setting fields</a></li>
<li class="tab col s6"><a href="#form_click">Click the button</a></li>
</ul>
</div>
<div id="form_simple_submit" class="col s12">
<pre class="language-yaml">
<code class="language-yaml">- find:
form: "form#form1"
do:
# SUBMITTING THE FORM
- submit
</code></pre>
</div>
<div id="form_field_set" class="col s12">
<pre class="language-yaml">
<code class="language-yaml">- find:
form: "form#form1"
do:
# FILLING OUT THE FORM FIELDS WITH VALUES
- fields_set:
textfield: 10442
checkbox: no
select1: yes
# SUBMITTING THE FORM
- submit
</code></pre>
</div>
<div id="form_click" class="col s12">
<pre class="language-yaml">
<code class="language-yaml">- find:
form: "form#form1"
do:
# FILLING OUT THE FORM FIELDS WITH VALUES
- fields_set:
textfield: 1023
checkbox: yes
select1: no
# SUBMITTING THE FORM BY CLICKING THE BUTTON
- click: submitbutton
</code></pre>
</div>
</div>
<span class="spacer"></span>
<p class="flow-text">
Next, we'll learn how to work with the register and what commands you can use to manipulate it.
