我遇到了头痛的情况。当我检查选择选项（05/30/2012 EQ）时，我无法单击选择按钮来提交操作，但我应该能够单击它。这个问题发生在 Chrome 和 IE 上，但对 FF 来说很好。我认为这是一个 Jquery 不兼容问题。我附上了我的一些代码如下：

  function $recalcSelection($checkbox) {
    $selectActionList.find("option").each(function() {
      $optionLength = $table.find("td.actioncolumn input:checked").length;
      if($optionLength <= 0) {
        $(this).attr("disabled", true);
      } else if($optionLength == 1) {
        $(this).attr("disabled", false);
      } else {
        if(
          $(this).val() == "editAppointment" ||
          $(this).val() == "copyAppointment" ||
          $(this).val() == "viewShowList" ||
          $(this).val() == "viewScheduledTimes")
        {
          $(this).attr("disabled", true);
        } else {
          $(this).attr("disabled", false);
        }
      }
    });

    if($selectActionList.find("option:selected").attr('disabled')) {
      $selectActionList.find("option:enabled").eq(0).attr("selected", true);
    }

    if($selectActionList.find("option:enabled").length <= 0) {
      $selectActionButton.attr("disabled", true);
    } else {
      $selectActionButton.attr("disabled", false);
    }
  }

$selectActionButton 是提交按钮，$selectactionlist 是选择列表。我试图在 Chrome 中打印 ($selectActionList.find("option:enabled").length，它是 0。但是当我在 FF 中打印它时，它是 7。谁能帮我找出原因？我会的欣赏它。谢谢

我附上了一些 HTML 表格，如下所示：

<table id="appointmentTable">
  <thead>
    <tr class="headerrow">
      <th class="actioncolumn"></th>
      <th class="datecolumn">Date</th>
      <th class="earliesttimecolumn">Start Time</th>

      <th class="clientnamecolumn">Client</th>
      <th class="locationcolumn">Location</th>

      <th class="typecolumn">Type</th>
      <th class="filledtimescolumn">Filled Times</th>
    </tr>

  </thead>

  <tbody> 

      <tr class=" hiddenrow" appointmentid="15166">

而不是执行以下操作：

    if (foo) {
      $(this).attr("disabled", true);
    } else {
      $(this).attr("disabled", false);
    }

您应该添加和删除 disabled 属性，因为有时只是 disabled 属性的存在可以使其禁用（可能是 chrome 保持禁用它的原因）。试试这个：

if (foo) {
    $(this).attr("disabled", true);
} else {
    $(this).removeAttr("disabled");
}

编辑：试试这个确切的代码

function $recalcSelection($checkbox) {
    $selectActionList.find("option").each(function() {
        $optionLength = $table.find("td.actioncolumn input:checked").length;
        if($optionLength <= 0) {
            $(this).attr("disabled", true);
        } else if($optionLength == 1) {
            $(this).removeAttr("disabled");
        } else {
            if($(this).val() == "editAppointment" ||
                $(this).val() == "copyAppointment" ||
                $(this).val() == "viewShowList" ||
                $(this).val() == "viewScheduledTimes")
            {
                $(this).attr("disabled", true);
            } else {
                $(this).removeAttr("disabled");
            }
        }
    });

    if($selectActionList.find("option:selected").attr('disabled') != "true") {
        $selectActionList.find("option").filter(function () { return $(this).attr("disabled") != null}).eq(0).attr("selected", true);
    }

    if($selectActionList.find("option").filter(function () { return $(this).attr("disabled") != null}).length <= 0) {
        $selectActionButton.attr("disabled", true);
    } else {
        $selectActionButton.removeAttr("disabled");
    }
}​
