jquery - 将 margin-left 添加到 div

Question

我这里有很多 div，我想将 55px 添加到所有 margin-left，而不是将它设置为 55px，而是将它添加到已经存在的部分，这里有一些代码。

$("#AfirstObj,#AsecondObj,#AthirdObj,#AfourthObj, #AfithObj,#AsixthObj,#AseventhObj,#AeightObj,#AnineObj,#AtenthObj,#AeleventhObj,#AtwelveObj,#AthirteenObj,#AfourteenObj,#AfifthteenObj,#AsixteenObj, #AseventeenObj,#AeighteenObj,#AnineteenObj").what do i add here? ;

Answer 1

遍历它们并将 55 添加到当前 margin-left 值。

$("#AfirstObj,#AsecondObj,#AthirdObj,#AfourthObj, #AfithObj,#AsixthObj,#AseventhObj,#AeightObj,#AnineObj,#AtenthObj,#AeleventhObj,#AtwelveObj,#AthirteenObj,#AfourteenObj,#AfifthteenObj,#AsixteenObj, #AseventeenObj,#AeighteenObj,#AnineteenObj").each(function() {
  $(this).css('margin-left', function(i, val) {
    return String(parseInt(val) + 55) + 'px';
  })
});

工作示例。

$('#one, #two, #three, #four').each(function() {
  $(this).css('margin-left', function(i, val) {
    return String(parseInt(val) + 55) + 'px';
  })
})

#one, #two, #three, #four {
  display: inline-block;
  width: 100px;
  height: 100px;
  background: tan;
}
#one, #three {
  margin-left: 5px;
}
#two, #four {
  margin-left: 55px;
}

<div id="one"></div>
<div id="two"></div>
<div id="three"></div>
