我想设置一个表单,用户可以在其中从一组单选按钮中进行选择,如果他们不喜欢任何选择,他们可以使用最后一个单选按钮,该按钮将有一个文本字段,他们可以在其中输入自定义文本.
I wanna set up a form where users can choose from a set of radio buttons and if they dont like any choice they can use the last radio button which will have a text field to it where they can enter the custom text.
我在一些网站上看到过这个.只是想知道它是在哪里以及如何实现的
i have seen this on a few sites. just wondering where and how it was implemented
我给你做了个例子,这是你想要的吗?http://www.jsfiddle.net/T7gE7/
I made you an example, is this what you wanted? http://www.jsfiddle.net/T7gE7/
var temp = '';
function disableTxt() {
var field = document.getElementById("other");
if(field.value != '') {
temp = field.value;
}
field.style.display = "none";
field.value = '';
}
function enableTxt() {
document.getElementById("other").style.display = "inline";
document.getElementById("other").value = temp;
}
