Force button click based on a specific event
<p>Sorry if my question I won't include too much code but I am new with Javascript.
I need to create a script that will take the value from this HTML code:</p>

<pre><code>&lt;span class="bianco" id="contatore_139287"&gt;91.5&lt;/span&gt;
</code></pre>

<p>If the value is lower than 0.9 the javascript function should force the click of the following button:</p>

<pre><code>&lt;input type="button" value="PUNTA" onclick="puntal7h5n6o1ut5ovslhtou7ii2gu6(139287);" id="bottone2139287"&gt;
</code></pre>

<p>It will be installed on my browser to automate the process of clicking a button on my own website when that specific event happens ( value is lower than 0.9 as explained above )</p>

<p>Could you help?</p>
