each

问题 Example here: http://jsfiddle.net/KyW6c/2/ I have an ordered list. Each list item is a project in my portfolio. I'm writing some jQuery that will move a clicked list item up to the top left of the ordered list. I've accomplished this, but the problem I'm encountering is that the list items below the clicked one are shifting. This code is provided in the fiddle (commented out). The solution I'm attempting to implement will set each list item's position to absolute and left and right to it's

问题 I have this code block I find particularly long and hard to udnerstood : the call stack is full of implicit functions and paramters implicitely added to it. in other words, i would like to clarify my code by separating the function called in the each from the each itself. Look that example : $(xml).find('group').each(function () { var groupName = $(this).attr('name'); // There is here around 100 lines of codes I would like to split in // at least five functions, And I'm sure it is possible to

问题 I have a 10x10 array representing 10 rows with 10 cells each. I want to draw a grid and set each cell's background-color according to the value in the array: a 0 value will be white and a 1 value will be black I've set up this CSS: .cell{ height: 20px; width: 20px; float: left; margin: 0; padding: 0; } .cell.live{ background-color: black; } .cell.dead { background-color: white; } I created a helper that will return 'live' or 'dead' according to the value in the array according to 2 arguments:

问题 I'm working yet on a small script to capture keyevents and easily bind functions on them. But I'm stuck for now! The problem is, that if I initalize more than one "eventhandler" it overides arguments from the first initialization. Thousands of words do not say more than some lines of code. So, here's what I've done so far: var keyCodes={a:65,b:66,c:67,d:68,e:69,f:70,g:71,h:72,i:73,j:74,k:75,l:76,m:77,n:78,o:79,p:80,q:81,r:82,s:83,t:84,u:85,v:86,w:87,x:88,y:89,z:90,"0":48,"1":49,"2":50,"3":51,

问题 Some sources ask to prefer "for loop over $.each()" in jquery since $.each() is slower than for loop in ops/sec Is this because of callback function of $.each()? Can anybody explain Why $.each() is slower than for loop in jquery and In which case i have to choose for loop over $.each() or vice verse ? Thanks in Advance. 回答1: This code comes from within the jQuery.each method: for ( ; i < length; i++ ) { value = callback.call( obj[ i ], i, obj[ i ] ); if ( value === false ) { break; } } So

问题 I'm sure there are a million things wrong with my coding... However everything works EXCEPT - the autoComplete. I can't seem to return values from my searchResults function. I want to return the string. Right now alert("t: " + availableTags); works BUT alert("x: " + availableTags); does not Neither return lines return the values. What am I doing wrong? $(function(){ //$("#searchButton").click(function(){ //$("input").keyup(function(e){ var availableCompanies = searchResults('CompanyName'

问题 I'm working with the jQuery ColorPicker widget - specifically exercising the ColorPickerSetColor function (just 'setColor' internally). Code excerpt: setColor: function(col) { if (typeof col == 'string') { col = HexToHSB(col); } else if (col.r != undefined && col.g != undefined && col.b != undefined) { col = RGBToHSB(col); } else if (col.h != undefined && col.s != undefined && col.b != undefined) { col = fixHSB(col); } else { return this; } return this.each(function(){ if ($(this).data(

问题 WordPress add an extra 10px to the .wp-caption container when a caption in present. I'm trying to use jQuery to remove the extra 10px. I've been able to do this thanks to the answers in this question, but I realized that b/c there are sometimes multiple images in a post, I need to use something to the effect of .each() to iterate. The code below works for the first image but then wrongly applies the first image's with to the container of the second image. How can I correct the .each() to work
