问题 I want the cursor/line thing in the text box to automatically start blinking when the page loads. I've tried contentEditable="true" but that's not working 回答1: You have to set focus on the text box. This can be done either by JavaScript document.getElementById("fname").focus(); or Jquery $( "#fname" ).focus(); or HTML5 <input type="text" name="fname" autofocus /> 回答2: In HTML5, you can simply use the input autofocus attribute. However, beware that this does not work in some versions of IE. 来源

问题 I have a camera in my app and I want to make it auto focus continuously in the same way that the phone's camera does it. I found the modes FOCUS_MODE_CONTINUOUS_VIDEO and FOCUS_MODE_CONTINUOUS_PICTURE , but they are not supported by some of the HTC Gingerbread phones I'm testing on.
