我试图通过单选按钮验证性别。这是我的代码。但它不起作用。 的JavaScript
function checkgender() {
var gen = document.subscribe.gender[0].checked;
var gen1 = document.subscribe.gender[1].checked;
if((gen==false)&&(gen1==false)) {
alert('Please Select your Gender Type!');
return false;
}
return true;
}
html
<input type="radio" name="gender" value="male" id="gender">male
<input type="radio" name="gender" value="female" id="gender">female
<input name="but" type="button" value="Add" class="btn btn-primary" onClick="checkgender()" />

答案 1 :(得分:0)
var gen = document.subscribe.gender[0].checked;
var gen1 = document.subscribe.gender[1].checked;
而不是使用
var x = document.getElementById(“gender1”)。value;
var x = document.getElementById(“gender2”)。value;
HTML
<input type="radio" name="gender" value="male" id="gender1">
<input type="radio" name="gender" value="female" id="gender2">
