    text
    copied!<p>So I am trying to randomize whether I am adding or subtracting. right now in this code what should happen is when I navigate to the #second page the code will load a new Problem is created. Inside the Problem function is should get a random number 0 or 1 and then based on that number the variable symbol should be set to a plus sign or a minus sign. This is not occurring.</p> <p>So my question is: Can I set a variable to a javascript operator sign? </p> <p>In this code below it never writes to the screen because it doesnt like me to set a variable to a + - sign? code in question:</p> <pre><code>$(document).delegate("#second", "pageshow", function(){ var problem = new Problem; function Problem (){ var num = Math.floor(Math.random()*2); var symbol; if(num) symbol = +; else symbol = -; $(".random").html(num + " " + symbol); } }); </code></pre> <p>here is my html: </p> <pre><code>&lt;/script&gt; &lt;div data-role="header" data-position="fixed"&gt; &lt;h1&gt;Hello&lt;/h1&gt; &lt;/div&gt;&lt;!-- /header --&gt; &lt;div data-role="content" id="timer"&gt; &lt;a href="#main" data-role="button"&gt;main&lt;/a&gt; &lt;p class="random"&gt;&lt;/p&gt; &lt;/div&gt;&lt;!-- /content --&gt; &lt;div data-role="footer" data-position="fixed"&gt; &lt;h4&gt;Goodbye&lt;/h4&gt; &lt;/div&gt;&lt;!-- /footer --&gt; &lt;/div&gt;&lt;!-- /page --&gt; </code></pre> <p>sorry should have mentioned that I actually want to use the operators later therefore I need to be able to assign the + or - is such a way that I can then perform legal math operations with them later.</p>
