我找到一个可以匹配以下内容的选择器时遇到了一些麻烦：

{

}
if(theme==2)
{
frgScreens=this.forecastThemes();
}
//Bind result to ViewPagerAdapter
adapter =new ViewPagerAdapter(this.getSupportFragmentManager(), frgScreens);
// Binds the Adapter to the ViewPager
this.viewPager.setAdapter(adapter);
addAndConfigureCirclePagerAdapter();
}

//#FIXME forecast2 problematic

});
mIndicator = (CirclePageIndicator) findViewById(R.id.indicator);
this.mIndicator.setBackgroundColor(Color.TRANSPARENT);

因此，如果我有$("input[data-rule-*]");
或data-rule-required，则需要匹配这两个属性。 （仅举例，我有一堆后缀，指定所有这些都不是一个选项）。
我发现只有data-rule-email选择器，不符合我的条件。
我看了一下这个主题：how do I find elements that contain a data-* attribute matching a prefix using jquery。问题是一样的，但我想知道是否有更紧凑的解决方案。
HTML示例。假设我可以拥有更多具有不同$("#element[attribute=value]")属性的输入：
data-rule-something答案 0 :(得分：2)
您的选项是向元素添加其他属性或标识符，以便您可以全部选择它们，或者在查询选择器中包含所有属性组合。
下面的示例为两个data-object元素添加了一个额外的input单例，然后查询该属性以更新字段值。
var dataObjects = document.querySelectorAll("[data-object]");
for(var i = 0, len = dataObjects.length; i < len; i++){
dataObjects[i].value = i;
}<input type="text" data-rule-required data-object />
<input type="text" data-rule-email data-object />
答案 1 :(得分：1)
一种不那么优雅的方式，但似乎它正在起作用：
$("input").filter(function() {
if(Object.keys($(this).data()).toString().indexOf('rule')!==-1) {
return $(this);
}
}).css('background-color','red');
