attr

问题 I've been working on a Custom Control for Android and although I tried to do what's suggested here there seems to be something I'm doing wrong. Here's my code to see if anyone can spot the problem: MyComponent.java public MyComponent(Context context, AttributeSet attrs) { super(context); TypedArray arr = context.obtainStyledAttributes(attrs, R.styleable.MyComponent); CharSequence myId = arr.getString(R.styleable.MyComponent_identifier); if (myId != null) { this.setIdentifier(myId.toString());

问题 android.R.attr.selectableItemBackground exists, but how do I add it programatically to an ImageButton? Also, how would I go about finding the answer in the documentation? It's mentioned here, but I don't see any explanation of how it's actually used.

问题 I'm trying to manipulate the svg 'viewBox' attribute which looks something like this: <svg viewBox="0 0 100 200" width="100" ...> ... </svg> Using $("svg").attr("viewBox","..."); However, this creates a new attribute in the element called "viewbox". Notice the lowercase instead of intended camelCase. Is there another function I should be using? 回答1: I was able to use pure javascript to get the element and set the attribute by using var svg = document.getElementsByTagName("svg")[0]; and svg

问题 I've searched and searched, and it seems I'm stuck on this problem. Somehow I thought this wouldn't be too hard, and it probably isn't for anyone with a little more knowledge about jQuery. I have an .html file, lets call it "originalfile.html", with a couple of lists, something like this: <div id="content"> <ul id="firstlist"> <li class="link1"><a href="/path/link1.html" target="_blank"></a></li> <li class="link2"><a href="/path/link2.html" target="_blank"></a></li> <li class="link3"><a href=

问题 I have a bunch of imgs inside a div with a class on them, in my JS I have a for loop that re-sizes the images to fir inside a box without stretching $('.gallery img')[i].attr('id', 'img' + i); This is what I tried to get each img to have its own id like 'img1' 'img2' 'img3' etc but it seems to not work 回答1: Replace your for loop with: $('.gallery img').each(function(i) { $(this).attr('id', 'img' + i); // You can also add more code here if you wish to manipulate each IMG element further });
