<p>Depending on the browser, there are several methods by which a link can be "clicked" using javascript.</p>
<p>IE (pre IE9)</p>
<p>element.click();
element.fireEvent('click');</p>
<p>Other browsers use:</p>
<p>element.dispatchEvent(evt) where evt is a mouseclick event.</p>
<p>I want to make sure that actual end user action was the originator of the event on particular links. The technique I use now is to override these methods and filter out click events, but it is easily defeated by reverting the methods back to the prototype versions before using them.</p>
<p>Is there any reliable, cross browser way to determine whether or not a click event is firing as a result of direct user action (they actually clicked the element).</p>

221,708 | 221,709 | Basic decrement loop - PYTHON | <p>Newbie to python and hit a snag in my latest program. Simply put, I'm trying to code up a decrement loop for a user input variable if possible. Essentially I have a global constant set to value e.g. 13, each time the program loops it prompts the user to input a value then that user value is shaved off 13 until it reaches 0. Problem is that it does shave it off but when it reiterates it resets the value to 13 and only removes the current iterate value entered. So if you enter 2 each iteration it just takes it down to 11... But I'm aiming for a result using 2 as an example again, 11, 8, 5, etc etc or using 3 as an example 10, 7, 4.... Any help guys will be much appreciated, cheers :)</p>

while other_input_var > 0: # guys this is my main score accumulator

if b != 0:

<p>What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have? I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.</p>

4,487,750 | 4,487,751 | Select element client side modification? | <p>I use tools like Firebug pretty routinely, and often build SPA style dynamic forms where DOM manipulation with user inputs is routine. Are there any safeguards against a user inserting options into a select box using a tool like Firebug or any sort of javascript CLI?</p>
<p>As a simple example, consider this select box for you to choose whether you are married or unmarried (My actual select boxes have MANY more options, and are populated via AJAX from XML files. This will be important later.):</p>
<pre><code><select name="mstatus" id="mstatus">
<option value="" selected>Specify marital status</option>
<option value="Married">Married</option>
<option value="Single">Single</option>
</select>
</code></pre>
<p>Currently I can easily insert another option thusly (I have Mootools on the page):</p>
<pre><code>$('mstatus').innerHTML+="<option value='Rebel'>I won't play by the rules</option>"
</code></pre>
<p>Now of course for this example, I can check server side whether the selected option is valid without too much grief. But generally I would have to compare the user submission to the original XML source for each select in order to confirm its validity. </p>
<p>Is there another way to ensure the integrity of returned values? Is this enough of a non issue for me to take user selection at face value? Is the best practice here really just to treat all select inputs as text inputs until you have confirmed they are selected from within their valid range of values?</p>
<p>Thanks for your help.</p>
<p>Note: There is no danger of code injection, since all values entered are thoroughly vetted and are pretty inert by the time they get popped into the database.</p>
