问题 This is not a duplicate. Previous questions relate to IE8. This is occurring in IE11. I have no problems running this in Chrome or Firefox, but my code must function in IE11 and I am receiving the following error: Object doesn't support property or method 'getElementsByClassName' function showNext(a) { var questions = document.getElementsByClassName("questionholder"); showRequired.style.display = "none"; for (var i = 0; i < questions.length; i++) { questions[i].style.display = "none"; } var

问题 i often use this notation when i name my controls in order to get an array in POST or GET. <input name="color[1]" type="text" /> <input name="color[2]" type="text" /> <input name="color[3]" type="text" /> so in my scripts i can do <?php $data=$_GET["color"]; for each ($color as $key=>$value) { doSomething(); } ?> Often happens that i need to get those id back in javascript , but i cannot get them , so i often add an ID to each element in html like that <input name="color[3]" id="color_3" type

问题 I'm trying to complete this form : http://www.lbalberti.it/whatsup.asp?codist=57247 I was able to insert value to the two textbox but the button doesn't work. @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home_page); final String user = getIntent().getStringExtra("username"); final String psw = getIntent().getStringExtra("password"); MyWebView view = new MyWebView(this); view.getSettings()

问题 I use this code: <div name="1234"> <img src="pic.gif" height="70" width="100" onMouseOver="clear('1234')"> </div> And: function clear(element_name){ document.getElementsByName(element_name)[0].innerHTML=""; } It does work in Firefox and Opera, but doesn't work in IE 6.0 or IE 8.0, and probably not even in newer IE's. What to do? 回答1: Well, the problem is this: IE understands document.getElementsByName(...)[0] as document.getElementById(...). So if you would define also an id for your element,

问题 As I know, getElementsByName is a function defined in HTMLDocument ,and HTMLDocument inherits from Document ,and Document inherits from Node . So why I can see Document.prototype.getElementsByName in Chrome but not Firefox?Does not Chrome implement DOM2 spec? 回答1: Does not Chrome implement DOM2 spec? Yeah, probably not. I'd guess they at least implement DOM 3, if not a more current version :-) However, those don't define a getElementsByName either. So how did they get this? It is actually

问题 this question sounds stupid but how come when I use the function GetElementsByTagname("frame") , it only returns 3 as a length and not 5 as I expected ? Here is the HTML of the webpage where I counted 5 times the apparition of the tagname "frame" but when I ask for the length in VBA I get 3... My observations : 1) You can see that 3 is the number of main frames (top_navigation, contentframe, dummyframe) 2) If I try to access to one of the mainframes via getelementbyname, it works but if I try
