Question

我的简单jQuery脚本在IE中不起作用。

请帮忙。

整个HTML代码在这里：

<script type="text/javascript" src="jquery-1.4.2.min.js" ></script>
<script type="text/javascript">
$(document).ready(function() {
        var cvalue = $(".space").css("backgroundColor");
        $(".space").css("color",cvalue);    
   });
</script>

<style>
table.tdata td {
    padding: 10px;
}
tr.zrow1 {
    background-color: #ccc
}
tr.zrow2 {
    background-color: #aaa
}
tr.zrow1 td, tr.zrow2 td {
    border-top: 1px solid white;
    border-left: 1px solid #ccc;
}
table.tdata tr.thead1 {
    text-align: center;
}

table.tdata tr.thead {
    background-color: #003;
    color: white;
    text-align: center;
}
.thrColFixHdr #header h1 {
    margin: 0; 
    padding: 10px 0; 
}
.thrColFixHdr #mainContent {
    margin: 0 200px; 
    padding: 0 10px; 
}
</style>

我认为IE不了解css中的透明值，任何解决方案？

最终解决方案：

$('.space').each(function(index, value){
var cvalue = $(".space").css("backgroundColor");
if(cvalue == '' || cvalue == 'transparent'){
 var pcolor = ($(this).closest('div, p, tr').css('backgroundColor'));
 if (pcolor == '' || pcolor == 'transparent'){
  //this means the closet tag hasnt any bgcolor and it is white 
      $(this).css('color','white');
 }else {
  $(this).css('color',pcolor);
 }
}else{
 $(this).css('color',cvalue);
}
});

您在代码末尾缺少一个半冒号添加它，它应该没问题 - http://jsbin.com/anuric/2/

$(document).ready(function() { var cvalue = $(".space").css("background-color"); alert(cvalue); $(".space").css("color",cvalue); });

更新

<script type="text/javascript">
    $(document).ready(function() {
        var cvalue = $(".space").css("background-color");
        alert(cvalue);
        $(".space").css("color",cvalue);    
    });
</script>

使用您的HTML更新 http://jsbin.com/asigah/

Update2 - 确保CSS中有.space background-color的CSS值，如果不存在，则cvalue无法找到.space的背景颜色。

.space { background-color: #fff; }

更新3 - 如果你只是想“隐藏”.space的内容而只是在那里有一个空的空间，那么就使用它;

$(document).ready(function() {
    $('.space').replaceWith('&nbsp;'); 
});

这里的工作样本; http://jsbin.com/asigah/3

更新4;

$(document).ready(function() {
  $('.space').each(function(index, value){
    var cvalue = ($(this).closest('div, p, tr').css('background-color'));
    //alert(cvalue);
    $(this).css('color',cvalue);
  });
});

这将找到最接近的元素（div，p或tr）标签，并将.space的颜色设置为与其找到的元素的背景颜色相同。我想这就是你想要的。

Answer 2

如果您使用 {{1> .space 添加背景颜色，此代码将有效}}

css

注意：

代码有效。但它为$(document).ready(function() { var cvalue = $(".space").css("backgroundColor"); $(".space").css("color",cvalue); });添加了transparent颜色，因为.space .space没有定义任何背景。因此，您需要将css颜色添加到backgound。

此代码适用于您当前的HTML和CSS结构，不做任何更改：

.space

我添加了另一个代码段：

$(document).ready(function() { $('.space').each(function(index, value){ var cvalue = $(this).parents().find('tr').css('backgroundColor'); $(this).css('color', cvalue); }); });
