通过单击单选按钮禁用 - 启用超链接 [英] disable-enable a hyperlink by clicking on radio-buttons
问题描述
我有一个超链接代码，如：
点击这里
我希望根据我的单选按钮点击自定义此链接，如：
YES
NO
对应单选按钮值：'yes'，我想启用超链接。
在单选按钮值时：'no'，我想禁用超链接。
所以，为了在单击单选按钮'NO'后禁用超链接，我在disable-link（）方法中写了以下内容：
function disable-link（）
{
//document.getElementById('disable-link').disabled=true;
document.getElementById（'disable-link'）。href ='＃';
}
现在，我必须在enable-link（）方法中编写，以便在单击单选按钮'YES'后重新启用超链接
i have a hyperlink code like : Click Here and i want to customize this link on the basis of my radio button click,which are like : YES NO on radio-button value:'yes',i want to enable the hyperlink. while on radio-button value:'no',i want to disable the hyperlink. So,to make the hyperlink disable after clicking radio-button 'NO', i have written the following in disable-link() method : function disable-link() { //document.getElementById('disable-link').disabled=true; document.getElementById('disable-link').href = '#'; } Now,what i have to write in enable-link() method so that the hyperlink gets re-enabled after clicking radio-button 'YES'
function enable-link()
{
//document.getElementById('disable-link').disabled=false;
// SOME LINE OF CODE TO RE-ENABLE THE LINK
}
document.getElementById（'disable-link'）。disabled = true * / * false; - ：它会禁用，但用户可以点击超链接。所以，我使用了 document.getElementById（'disable-link'）。href ='＃'; - ：它使得链接也无法点击
请建议。
document.getElementById('disable-link').disabled=true*/*false; -: it makes the disable but user is able to click on the hyperlink though.So, i have used "document.getElementById('disable-link').href = '#';" -: it makes the link unclickable too Please suggest.
