我想在具有“只读状态”类的字段中删除属性名称以“data-val”开头的所有属性
jQuery("[data-val^='tr']" )
这将给出以'tr'
开头的属性'data-val'值但我需要删除以...开头的所有属性 匹配元素中的'data-val'。
我该怎么做?

您可以使用vanilla javascript的attributes
:
$('.read-only-state').each(function() {
// get the native attributes object
var attrs = this.attributes;
var toRemove = [];
// cache the jquery object containing the element for better performance
var element = $(this);
// iterate the attributes
for (attr in attrs) {
if (typeof attrs[attr] === 'object' &&
typeof attrs[attr].name === 'string' &&
(/^data-val/).test(attrs[attr].name)) {
// Unfortunately, we can not call removeAttr directly in here, since it
// hurts the iteration.
toRemove.push(attrs[attr].name);
}
}
for (var i = 0; i < toRemove.length; i++) {
element.removeAttr(toRemove[i]);
}
});
