<p>I have 4 input textfields, and a single textfield that should extract its value and distribute them into each separate input using index.
I am expecting a reverse process (from the previous question) to get default value from <strong>distributor</strong> to be distributed/ populated into <strong>distributed</strong> textfield. Each value is pipe delimited.</p>
<pre><code><input type="text" value="Data 1 | Null | Data 3 | Data 4" class="distributor">
<input type="text" class="distributed">
<input type="text" class="distributed">
<input type="text" class="distributed">
<input type="text" class="distributed">
</code></pre>
<p>The distributor has an array-like value string: Data 1 | Null | Data 3 | Data 4</p>
<p>Null is accepted from original process, simply to maintain the process of explode and implode by PHP.</p>
<p>So input#1 will recieve Data 1, etc in an indexed manner, hopefully, because the order is fixed and using <strong>name</strong> attributes seems redundant.</p>

<p>(technically this is only for my "release version", where I append all my files together into a single file and surround them with the above....my dev version still has typically one global per js file)</p>
<p>This all works great except for one thing...there is one important place where I need to access some of these "globals" by string name. Previously, I could have done this:</p>
<pre><code> var name = "g";
alert (window[name]);

<p>and it did the same as</p>

<p>Now -- from inside the block -- I would like to do the same, on my pseudo-globals. But I can't, since they are no longer members of any parent object ("window"), even though are in scope.</p>

395,771 | 395,772 | Multiple return statements vs Multiple goto statements : which one would be preferable? | <p>I read that both multiple returns and multiple goto statements are bad programming practice. I have a function which can detect some 8 types of errors. In case of error, should i return error code or should i use goto statment to go to end of function and return from there.
Whenever memory freeing is required before returning from function, i thought it would be better to have a goto end and free the memory at the end of the function(so that only one free is enough in function)</p>
<p>However, In my function, memory is not allocated.
In this case which one is preferable ? Multiple returns or multiple goto statements ?
Or can we avoid both ?</p>
<p>EDIT: Some way to avoid both is, pass parameter to function which can store errorType. Samething can be checked inside function before proceeding further. But this too makes the code ugly.</p>

<p>I must be able to match the likes of Å, é and '. I think 123 is also a word. I even think 1:e and 1st are words... </p>
<p>How would I proceed if I wish to match words from Russian and Japanese also. </p>
<p>Thanks,</p>
<p>Barry</p>
<p>P.S. The following are not words and should not be matched:</p>
<p><br>, =HELLO=, @NEW_LINE_MARKER, can"t, hel*o, /new/</p>
<p>Also, </p>
<p>This string "Hey! What? Yes, I'm coming." should be split into:</p>
<p>(Hey,
What,
Yes I'm coming)</p>

1,012,842 | 1,012,843 | Creating anonymous dynamic runtime instances | <p>How can I create implementations of an interface dynamically at runtime in java?</p>
<p>I have a factory that will read the annotations on class Foo and create an instance of class Bar. For this factory to be type safe, I'd like my client factories to be interfaces with a factory method that takes type Foo and returns type Bar. I then want my factory to implement this factory method at runtime.</p>
<p>All of this is because the factory code would be redundant and hard to maintain. If generated at runtime, it would always be current.</p>
<p>Example:</p>
<pre><code>public class Foo{
private String name;
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
public class Bar{
private String personName;

}
public void setPersonName(String personName){
this.personName= personName;
}
}

Bar create(Foo foo);
