问使用量角器获取所有元素属性

EN

Element.prototype.getAttributes = function() {
    return (function (node) {
        var attrs = {};
        for (var i=0;i<node.length;i++) {
            attrs[node.item(i).name] = node.item(i).value;
        }
        return attrs;
    })(this.attributes);
};

var myElement = element(by.id('myId'));
expect(myElement.getAttributes()).toEqual({'attr1': 'value1', 'attr1': 'value1', ... });

browser.executeScript('return arguments[0].dataset;', elm).then(function (attrs) {
    console.log(attrs);
});

var elem = element(by.id('runButton'));
browser.executeScript("return arguments[0].attributes", elem.getWebElement())
    .then(function (attrs) {
        console.log(attrs.length);    // outputs numbers of attributes.
        // access collection of Attr objects
        console.log(attrs[0].isId);   // outputs `true`
        console.log(attrs[0].name);   // outputs `id`
        console.log(attrs[0].value);  // outputs `runButton`
    });
