问在javascript中按属性删除对象

EN

var tables = document.getElementsByTagName('table');
for(var i = 0; i < tables.length; i++){
    if(tables[i].getAttribute('width') == "25%"){
        tables[i].parentNode.removeChild(tables[i]);
    }
}

var x = document.querySelectorAll("table[width='25%']");
for (var i=0; i<x.length; i++) { //returns array of elements that match the attribute selector
    x[i].remove(); //call prototype method defined below
}

Element.prototype.remove = function() {
    this.parentElement.removeChild(this);
}
NodeList.prototype.remove = HTMLCollection.prototype.remove = function() {
    for(var i = 0, len = this.length; i < len; i++) {
        if(this[i] && this[i].parentElement) {
            this[i].parentElement.removeChild(this[i]);
        }
    }
}

$("[attribute=value]").remove()
