Javascript not compatible with jQuery v1.11 or below -


i want write small script invert black , white colors on area of page. used inverting script found on thread , adjusted invert black , white , on area of page: http://jsfiddle.net/yqe9t/87/

this works fine on jquery 1.12.1 , above ive noticed of pages im working still use jquery 1.9 , reason script not work on there; http://jsfiddle.net/yqe9t/88/ (jquery 1.9 here). i'm unable change jquery version used on pages need make compatible that.

can please me figure out how make code work on older versions well? i'd work on new , old dont know enough javascript myself fix it.

my complete javascript:

$(".invertall").click (function () {     var body   = $(".unit.size-col-d.width610");     invertelementcolors ( $(body) ); } );  function rgb2hex(rgb){  rgb = rgb.match(/^rgba?[\s+]?\([\s+]?(\d+)[\s+]?,[\s+]?(\d+)[\s+]?,[\s+]?(\d+)[\s+]?/i);  return (rgb && rgb.length === 4) ? "#" +   ("0" + parseint(rgb[1],10).tostring(16)).slice(-2) +   ("0" + parseint(rgb[2],10).tostring(16)).slice(-2) +   ("0" + parseint(rgb[3],10).tostring(16)).slice(-2) : ''; }  function invertelementcolors (jnode) {  jnode.children().each(function () {     invertelementcolors ( $(this) ); });  jnode.css ( {     'color' :               function (j, oldcolor) {         return invertrgb_colorstr (oldcolor);     },     'background-color' :    function (j, oldcolor) {         return invertrgb_colorstr (oldcolor);     } } ); }  function invertrgb_colorstr (oldcolorstr) {  // convert color rgb hex code can detect colors var = oldcolorstr; var colorhex = rgb2hex(help);  // convert black , white     if ((colorhex == '#000000') || (colorhex == '#ffffff')) {   //--- special case   if (oldcolorstr == 'transparent')   oldcolorstr = 'rgb(255, 255, 255)';    //--- color text in rgb format.  eg: rgb(1, 22, 255)   var colorarray  = oldcolorstr.match (/\((\d+),\s?(\d+),\s?(\d+)\)/);    var newcolorstr = $.map (colorarray, function (byte, j)                        {                           if (!j) return null;                            //--- invert decimal byte.                           return math.abs (255 - parseint (byte) );                       }                    ).join (',');    return 'rgb(' + newcolorstr + ')';  } else {         return oldcolorstr;  } }

the source map in 2 jquery version different.

one checking if value mapping on array before trying access property .length.

map: function( elems, callback, arg ) {         var length, value,             = 0,             ret = [];          // go through array, translating each of items new values         if ( isarraylike( elems ) ) {             length = elems.length;

the failing not:

map: function( elems, callback, arg ) {         var value,             = 0,             length = elems.length,             isarray = isarraylike( elems ),             ret = [];

so when regex fails, pass map null accessing property .length of null throws exception.

so solution if cannot upgrade jquery self, pass value map if oldcolorstr.match (/\((\d+),\s?(\d+),\s?(\d+)\)/); doesn't return null. stop exception.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
