See working jsfiddle <a rel=\"nofollow noopener\" target=\"_blank\" href=\"http:\/\/jsfiddle.net\/bozdoz\/gfUXM\/\">here<\/a>.<\/p>\n<p>First of all, you don&#8217;t need to create new arrays.  Just use the index of your circleCol or squareCol arrays to pull the color values from the availableColors array.<\/p>\n<p>Like this: <\/p>\n<pre><code>$.each(squareCol, function(index, className) {\n    cValue = avaibleColors[index];\n    var canvasClass=\".\"+className;\n...\n<\/code><\/pre>\n<p>Second, you don&#8217;t need to check if your canvasClass variable is null, because $.each() will pull each value of the array and no more; therefore, it will always pull a value for canvasClass, which in your case is the array key.<\/p>\n<p>If anything you should use <code>if (canvas.getContext){<\/code>  as described in the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/developer.mozilla.org\/en\/Canvas_tutorial%3ABasic_usage#Checking_for_support\">MDN canvas tutorial<\/a>.<\/p>\n<p>Hope this helps.  I kind of entirely redid the script, so I can&#8217;t say exactly where the problem was.  I know that it was difficult to get the combined arrays to work with the $.each() functions.<\/p>\n<h2>The problem was:<\/h2>\n<p>$.each() didn&#8217;t work on the combined arrays.  It did, however, work, if you used a for&#8230;in&#8230; loop.  See <a rel=\"nofollow noopener\" target=\"_blank\" href=\"http:\/\/jsfiddle.net\/bozdoz\/heYke\/\">JSFIDDLE<\/a>.<\/p>\n<p>Notice that you get nothing in console or in an alert if you tried to get the values from squareObj or circleObj.  I think it&#8217;s because it turned into an object.  But I&#8217;m not familiar with this, so I can&#8217;t say for sure.<\/p>\n<\/p><\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p>            <span class=\"d-none\" itemprop=\"commentCount\">8<\/span> <\/p><\/div>\n<\/div>\n<p>[ad_2]<\/p>\n<p>solved Jquery array from arrays <\/p>\n","protected":false},"excerpt":{"rendered":"<p>[ad_1] A simple for loop should be able to do this: for (x in i_array){ iv[ii_array[x]] = i_array[x]; v[iii_array[x]] = i_array[x]; } See jsfiddle here.
