Radio button change css when clicked

由 早过忘川 提交于 2020-01-06 19:36:56
问题 Please take a look at http://jsfiddle.net/JHMqG/ I'm trying to figure out how to change the background of the radio button when clicked. So far, I've been successful with the cat option, but I'm stuck at the dog option. I need the dog option to work because I want the background change to include the circle button. Please advise. Thank you. 回答1: See this: DEMO I changed a bit the HTML: <div> <input type="radio" name=1 Value=420 id="a1"> <label for="a1" class="radiostyle" >Cat ($420)</label> <

问题 When you type in wrong data it shows right errors but when you enter right information it doesn't do anything in radio button textbox. It doesn't return any error either.

问题 All, Have used this site a few times before and had some great replies so hopefully someone can help again. I want a set of radio buttons, so that when you click a button - you get another set below it. Then again, when you click one of the 2nd set of buttons, you'll get a third etc. Currently I have the following: <html> <head> <title>My Wizard</title> <script language="javascript"> function Display(question) { h1=document.getElementById("yes"); h2=document.getElementById("no"); h3=document

Scanning radio syslogs in Android

由 我们两清 提交于 2020-01-06 07:26:53
问题 I am trying to extract some information from Android (e.g. LAST_CALL_FAIL_CAUSE). Some of the information I found on Google suggests scanning the radio logs for this. However, I am not really sure how to scan these logs or how to pro grammatically access them. I searched for this on Google but couldnt find anything useful. Any ideas ? 回答1: LAST_CALL_FAIL_CAUSE belongs to the radio log, the meaning of the value defined by the vendor of modem. eg, LAST_CALL_FAIL_CAUSE = 16 means call failed

JQuery attr（）、prop（）测试

由 天涯浪子 提交于 2020-01-05 05:05:25
attr（）、prop（）在介绍中都可以设置属性、获取属性值，本文只是针对一个 radio的简单测试； 　　<input type="radio" id = "isForeign2" checked="checked" /> or <input type="radio" id = "isForeign2" checked /> 一、取值不同： 　　attr（）取值为String，如果获取当前标签上不存在的属性，例如第二个input上的name属性，则为undefined； 　　prop（）取值为String或者状态，如果获取当前标签上不存在的属性，例如第二个input上的name属性，为""； 　　 or 二、当前input type=“radio"时，会存在radio的一些属性值，对radio的属性进行取值 　　以此为例：radio中存在一个默认的属性：defautChecked；（详情参考：http://www.runoob.com/jsref/dom-obj-radio.html） 　　1、获取值 　　attr("defaultChecked")；获取时，会得到undefined； 　　prop("defaultChecked")；获取时，可以得到当前radio的选中状态； 　　 　　2、设置属性 　　attr("checked",true); or attr(
