How can I extract the string from a certain data
attribute via regexp.
<button data-loading-text="Some text on loading" data-toggle="button">Button</button>
<button data-finished-text="Some text on finished" data-toggle="button">Button</button>
And my javascript is
var Buttons = document.querySelectorAll([data-toggle="button"]);
[].forEach.call(Buttons, function (item) {
var data = item.getAttribute('data-'+INEEDTHIS+'-text')
var option = INEEDTHIS
return new Button(item,option);
})
You can use the Element.attributes property:
var attrs = item.attributes;
for(var i = attrs.length - 1; i >= 0; i--) {
var m = attrs[i].name.match(/^data-(.*)-text$/);
if (m) {
var option = m[1];
// do something
}
}
您可以使用jQuery的.attr()
方法
