假设我正在寻找具有属性数据语言"的所有元素,其值以java"开头(将匹配java"和javascript").我知道该怎么做:
Say I'm looking for all elements with an attribute 'data-language', whose value begins with 'java' (would match both 'java' and 'javascript'). I know how to do this:
$('[data-language^="java"]')
但我的问题是:如何获取所有具有属性的元素(不是属性的值,而是实际的属性名称本身)?例如:
But my question is: how do I get all elements that have an attribute (not the value of the attribute, but the actual attribute name itself) beginning with something? For example:
没有捷径,可以使用attributes
集合:
There is no shortcut, you may use the attributes
collection :
$(someselector).filter(function(){
var attrs = this.attributes;
for (var i=0; i<attrs.length; i++) {
if (attrs[i].name.indexOf("someStartOfName")==0) return true;
}
return false;
});
