我有一个带有贝宝按钮的跨度。只有在用户确认TOS后,我必须使这个paypal按钮可用于按下。为此,我认为使用paypal按钮放置跨度另一个div与未选中的复选框,不透明度和z-index。用户检查复选框,并且叠加的div获得这样的z-index,因此带有paypal按钮的跨度将超过它并且可以被按下。
我需要像
这样的东西HTML
<div class="with_zindex">
<input type="checkbox">
<span class="here_is_paypal_button"></span>
</div>
CSS
.with_zindex{
background-color:#fafafa;
opacity: .5;
filter: alpha(opacity=50);
-moz-opacity: .5;
z-index:1000;
}
.with_zindex + input[type=checkbox]:checked {
z-index:-1000;
}
但是这对我不起作用(只有第一个格式化,不通过选中/取消选中复选框来修改)。

相反,您最初可以禁用PayPal按钮,并且可以在用户点击复选框后启用它。
<input type="checkbox" name="terms"
onclick="$('#paypal').removeAttr('disabled');" />
<input type="image" name="paypal" id="paypal" disabled="disabled" />
<input type="checkbox" name="terms"
onclick="document.getElementById('paypal').removeAttribute('disabled');" />
<input type="image" name="paypal" id="paypal" disabled="disabled" />
z-index
:您需要position: relative;
z-index
才能正常工作。并且没有否定z-index
!
.with_zindex {
background-color:#fafafa;
opacity: .5;
filter: alpha(opacity=50);
-moz-opacity: .5;
position: relative;
z-index:1000;
}
.with_zindex + input[type=checkbox]:checked {
position: relative;
z-index: 0;
}
<div class="with_zindex">
<input type="Checkbox" name="TOS" value="read">
<span class="catItemExtraFieldsValue">
<img src="http://gutgeordnet.de/reise/images/epaypal_de.gif">
</span>
</div>
.with_zindex {position: relative;}
.with_zindex input[type=checkbox] {
background-color:#fafafa;
filter: alpha(opacity=50);
position: absolute;
z-index: 50;
top: 10px;
left: -35px;
width: 135px;
text-align: right;
vertical-align: top;
cursor: pointer;
}
.with_zindex input[type=checkbox] + .catItemExtraFieldsValue {
position: relative;
opacity: .5;
-moz-opacity: .5;
z-index: 45;
}
.with_zindex input[type=checkbox]:after {
content: 'I accept';
font-size: 14px;
vertical-align: top;
line-height: 1em;
font-weight: bold;
font-family: tahoma;
}
.with_zindex input[type=checkbox]:checked {position: static; display: none;}
.with_zindex input[type=checkbox]:checked + .catItemExtraFieldsValue {
position: static;
background-color: transparent;
opacity: 1;
-moz-opacity: 1;
}

我是这样得到的:
<强> HTML:强>
<input class="Checkbox1" name="TOS" id="TOS" value="read" type="checkbox";"/>
<强> JS 强>
var $K2 = jQuery.noConflict();
$K2(document).ready(function(){
//$K2('#TOS').attr('checked', false);
//$K2('input[type=image]').attr("class", "agbunchecked");
//$K2('input[type=image]').bind("click", giveAllert);
if(!$K2('#TOS').attr('checked')) //Existenzcheck
{
$K2('input[type=image]').attr("class", "agbunchecked");
$K2('input[type=image]').bind("click", giveAllert);
}
function giveAllert()
{
alert("\Pleas check the checkbox!");
return false;
}
$K2('#TOS').change(function(event){
if(this.checked)
{
$K2('input[type=image]').attr("class", "agbchecked");
$K2('input[type=image]').unbind("click");
}
else
{
$K2('input[type=image]').attr("class", "agbunchecked");
$K2('input[type=image]').bind("click", giveAllert)
}
});
});
<强> CSS 强>
.agbunchecked{
background-color:#fafafa;
opacity: .5;
filter: alpha(opacity=50);
-moz-opacity: .5;
}
