389,409 | 389,410 | jQuery function has to repeat to work | <p>I'm just getting into jQuery and notice strange behavior in the way some of my code is executed. When I execute a function based on a click action, the function runs twice, the first time with an "undefined" value for the click and the second with the expected value. The end result is the code "works" but I want to understand what I'm doing wrong that is causing this unexpected behavior.</p>
<p>Here's my jQuery code:</p>
<pre><code>$(function() {
//$('#venue').buttonset().click(function(event, ui) {
//$( '#venue' ).buttonset().live('click', function (event, ui) {
$('#venue').buttonset().unbind('click').bind('click', function(event, ui) {
var venueName = $("input[name='venue']:checked").val();
if (venueName == "venue2") {
alert("About to deselect, venue: " + venueName);
$("#meallist option[value='Dinner']").removeAttr("selected");
} else {
alert("Doing nothing, venue: " + venueName);
}
});
});
</code></pre>
<p>Note the three different ways of expressing the click action at the top, derived from jQuery docs and previous answers on this site. All have the same outcome. You can try it here:</p>

<p>E.g. if the user did a post they'd get 5 points, if the user submitted a thread/topic they'd get 20 points and so on and the ranks would be like if the points are over M and lower then MX they'd be the R rank and so on.</p>
<p>M = The minimum points needed to gain the rank.</p>
<p>MX = The maximum points needed to gain the rank. </p>
<p>R = The Rank (e.g. Beginner, Master etc).</p>
<p>Hope all is clear, its a bit like the traditional forum points system where your given points for posts - which would give them a Display Title/Rank.</p>
<p>I'm currently storing the points within a MySQL DB, and assigning a Rank via PHP with if statements like so:</p>
<pre><code>if ($points > 0 && < 100) {
$rank = 'Beginner';
}

<p>Is their some sort of class, library, function, formula, method; you can suggest which could make this easier, or a better way you can think of?</p>

1,733,111 | 1,733,112 | Java Question mark inside println() | <p>I'm trying to make a program that solves equations, i want the answer to be displayed in the right way, if the number is negative, to display -x and not +-x,
for example,
Eq1: 4x-3 and not 4x+-3, but when it is positive to display 4x+3. I can't use the plus sign inside the quotations.
I wanted to use the ? : operator.
I tried something like this</p>
<pre><code>System.out.println("Eq1: "+ ((a11>0) ? (+ "+" + (int)a11) : + (int)a11) +"*x1+");
</code></pre>
<p>This line is supposed to print the negative number (i.e. it will be -2*x1) and if it's positive it should display the + sign and add the number, but it gives me an error around the + "+" +</p>
<p>Any thoughts? Thanks!</p>

It has lots of vars in it, like <strong>data: 'uid=' + <em>uid</em>, + '&othervars=' + <em>morevars</em></strong> etc, and <strong>each loop, the variables change</strong>.. so If put that [huge] part into a function() {} [Inside of a setTimeout(), using a counter in the loop to increment the timeout], when it executes, will the <em>actual value</em> be in place where I put the vars? </p>
