is there laravel4 html() function or way add disabled link. of course create <a> tag directly, though i'd prefer consistent. ie: {{ html::link('javascript:;','delete',array('id'=>"deletebt")) }} you must use link_to , example : link_to('link', 'title', array('id' => 'myid'));

in jquery, can combine promises follows: var promise = $.when(func1.execute(), func2.execute()); promise.done(function (data1, data2) { // code here } how rewrite using q? also. benefits of using q in scenario on jquery? simple answer: var promise = q.all([func1.execute(), func2.execute()]); promise.spread(function (data1, data2) { // code here }) .done(); annotated: //make `promise` promise array var promise = q.all([func1.execute(), func2.execute()]); //use spread spread array across arguments of function promise.spread(function (data1, data2) { // code here }) //use done errors thrown .done(); the concepts in q more defined. promise represents single value may not available yet. parallels synchronous code precisely. to represent multiple values then, use array. q.all helper method takes array of promises, , returns promise array containing fulfilled values. if promise in array rejected, resulting promise rejected. because in case know how l

i've got switch , if problem in javascript, code following. var a=0; if(a){ console.log("a true"); } else if(!a) { console.log("a false"); } else { console.log("a not true or false"); } switch(a){ case true: console.log("switch... true"); break; case false: console.log("switch... false"); break; default: console.log("switch... not true or false"); } when ran code above, got result in console confused me lot: a false switch... not true or false i think should this: a false switch... false anyone knows why happens? appreciate answers. if (!0) evalutes true. there rule non 0 in if evaluate true vie versa. but switch 0 explicitly checked against case values , 0 neither true or false , hence default statement gets executed.

i have several images need find edge. have tried following vision.edgedetector system object in matlab, , example give here: http://www.mathworks.com/help/vision/ref/vision.edgedetectorclass.html they give example hedge = vision.edgedetector; hcsc = vision.colorspaceconverter('conversion','rbg intensity') hidtypeconv = vision.imagedatatypeconverter('outputdatatype',single'); img = step(hcsc, imread('picture.png')) img1 = step(hidtypeconv, ing); edge = step(hedge,img1); imshow(edges); which have followed in code. however code doesn't produce edges like, seems though matlab can pick on half of edges in entire image. there different approach can take finding edges, or way improve upon vision.edgedetector object in matlab? by default hedge = vision.edgedetector has threshold value of 20. try changing hedge = vision.edgedetector('threshold', value ) , play value see value works out best you.
