}
function print_and_eval(data) {

eval(data);
}

<p><strong>Edit:</strong>
- It is safe to use eval() in my case. Please do not recommend this as a solution.
- The main problem is, that I have local variables in doSomething() which are not defined in print_and_eval(). The evaluation then leads to an 'ReferenceError: y is not defined' error.</p>
<pre><code>js> print_and_eval('var a = {x:1}')
var a = {x:1}

var target = $(this).attr(href).(strip the hashtag from the beginning of the link and output the resulting value);

2,876,642 | 2,876,643 | Javascript setInterval question | <p>I noticed something that I can't quite explain. I made this javascript code that grows or shrinks a blue box. The script is here:</p>
<pre><code>var animated = {
timer : null,
el : document.getElementById("divNavyBox"),
startGrowAnimation : function() {
this.stopAnimation();
this.timer = setInterval(
animated.doAnimation(5), 10);
},
startShrinkAnimation : function() {
this.stopAnimation();
this.timer = setInterval(function() {
animated.doAnimation(-5);
}, 10);
},
stopAnimation : function() {
clearInterval(this.timer);
},
doAnimation : function(amount) {
var size = this.el.offsetWidth;
if ((amount > 0 && size < 200) || (amount < 0 && size > 0)) {
this.el.style.width = size + amount + "px";
this.el.style.height = size + amount + "px";
} else {
this.stopAnimation();
}
}
};
</code></pre>
<p>When the startGrowAnimation method of the animated class is called, the box visually grows until it reaches a certain width and height. It then stops. The startGrowAnimation code is located below:</p>
<pre><code>startGrowAnimation : function() {
this.timer = setInterval(function() {
animated.doAnimation(5);
}, 10);
}
</code></pre>
<p>This code WORKS just fine. However, I don't understand WHY it's necessary to put an anonymous function in the parameter instead of just the normal call function. So, I replaced the code above with the code below:</p>
<pre><code>startGrowAnimation : function() {
this.stopAnimation();
this.timer = setInterval(animated.doAnimation(5), 10);
},
</code></pre>
<p>When I use this code, for some reason, the box only increases in size by five pixels each time the startGrowAnimation method is called. </p>
<p>So, why is it necessary to include the startGrowAnimation method inside of an anonymous function call in this case? </p>

555,670 | 555,671 | What is equivalent of RequestDispatcher#forward() Of Java in PHP? | <p>RequestDispatcher basically dispatches a request to some other resource i.e it doesn't do a redirect but simply forwards the page to some page(resource). Thus browser's history etc is not updated and the parameters that are available in <code>request</code> are still available on another page since we are not creating a new request using redirect.</p>
<p>What is equivalent of this in PHP? And also which function is used to redirect a page?</p>

463,956 | 463,957 | python zipfile basename | <p>I have some homework that I am trying to complete. I don't want the answer. I'm just having trouble in starting. The work I have tried is not working at all... Can someone please just provide a push in the right direction. I am trying to learn but after trying and trying I need some help.</p>
<p>I know I can you <code>os.path.basename()</code> to get the basename and then add it to the file name but I can't get it together.</p>
<p>Here is the assignment</p>
<p>In this project, write a function that takes a directory path and creates an archive of the directory only. For example, if the same path were used as in the example <code>("c:\\xxxx\\Archives\\archive_me")</code>, the zipfile would contain <code>archive_me\\groucho</code>, <code>archive_me\\harpo</code> and <code>archive_me\\chico</code>.</p>
<p>The base directory (<code>archive_me</code> in the example above) is the final element of the input, and all paths recorded in the zipfile should start with the base directory.</p>
<p>If the directory contains sub-directories, the sub-directory names and any files in the sub-directories should not be included. (Hint: You can use <code>isfile()</code> to determine if a filename represents a regular file and not a directory.)</p>
<p>Thanks again any direction would be great.</p>
