如何选中禁用/启用带复选框的按钮 [英] How to disable/enable a button with a checkbox if checked

问题描述

我需要一个脚本，可以与HTML代码一起使用，以在复选框被选中或取消选中时禁用/启用按钮，

< input type =submitname =sendNewSmsclass =inputButtonid =sendNewSmsvalue =Send/>

请好朋友，我不是说在检查时禁用按钮，而是相反。 解决方案

brbcoding已经能够帮助我使用我需要的适当编码，这里是它$ / b>
$ b

HTML

 < input type =checkboxid =checkme/> 
< input type =submitname =sendNewSmsclass =inputButtondisabled =disabledid =sendNewSmsvalue =Send/> 
  

Javascript

  var checker = document.getElementById（'checkme'）; 
 var sendbtn = document.getElementById（'sendNewSms'）; 
 //当未选中或检查时，运行函数
 checker.onchange = function（）{
 if（this.checked）{
 sendbtn.disabled = false; 
} else {
 sendbtn.disabled = true; 
} 
 
} 
  

Please i need a script that can work with the HTML code bellow to disable/enable the button when a checkbox is checked or unchecked,

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />

please pals i don't mean the button to be disabled when checked, but rather the other way round.
