[英]Using string methods to change DOM element parameters in Javascript Objects
If I have an object : 如果我有一个对象:
function myClass(id) {
this.em = document.getElementById(id);
this.html = function(data) {
this.em.html = data;
}
}
Now I can : 现在我能 :
var em = new MyClass("id");
em.html("NEW HTML HERE");
I need : 我需要 :
em.html = "NEW HTML HERE";
Is It possible? 可能吗?
In HTML5 you could define a set
method on the html
property (see defineProperty()
) 在HTML5中,您可以在html
属性上定义set
方法(请参见defineProperty()
)
function myClass(id) {
this.em = document.getElementById(id);
Object.defineProperty(this, 'html', {
set: function(val) {
this.em.html = val;
}
});
}
... but this will only work in the most modern browsers ; ...但是只能在最现代的浏览器中使用 ; IE8, Chrome 5, Firefox 4. IE8,Chrome 5,Firefox 4。
See a demo of the above working here; 在此处查看上述示例。 http://jsfiddle.net/sskKc/ http://jsfiddle.net/sskKc/
