  1. PO'for loop' and possible syntax error
    text
    copied!<p>Here is my current javascript. I know that it worked until I added the 'for loop'. The point of the for loop is to switch letters. As it stands, its checking to see if groups of 3 are equal to one letter. I will fix that later, but I know there must be a syntax error, as the buttons don't fade as my mouse moves over them. I know this is a stupid question and I'll kick myself when I see the error, but I'm tired and can't find it for my life right now. Also, is this for loop a valid way of changing letters? Is that the correct way to set an array value to the new letter?</p> <p>Here is the script.js:</p> <pre><code> $(document).ready(function() { $('#button_translate').mouseenter(function() { $('#button_translate').fadeTo('fast', 1); }); $('#button_translate').mouseleave(function() { $('#button_translate').fadeTo('fast', 0.7); }); $('#button_clear').mouseenter(function() { $('#button_clear').fadeTo('fast', 1); }); $('#button_clear').mouseleave(function() { $('#button_clear').fadeTo('fast', 0.7); }); $('#button_translate').click(function() { var dna = $('input[name=dna]').val(); var dna = dna.toUpperCase(); function allBases(text) { var bases = /^[ACGT]+$/; if(text.match(bases)) { var arr = text.match(/.{1,1}/g); /*document.write(arr + " is a DNA sequence.");*/ for (var i = 0; i &lt; (dna.length); i++) { if (arr[i]==='A') { arr[i]='U' }else if (arr[i]==='C') { arr[i]='G' }else if (arr[i]==='G') { arr[i]='C' }else if (arr[i]==='T') { arr[i]='U' }else{ document.write(dna + " is not a real DNA sequence. Error Code 2"); } } document.write(dna + " is the translated mRNA strand!"); }else{ document.write(dna + " is not a real DNA sequence."); } } allBases(dna); }); }); </code></pre>
