我需要知道如何隐藏“下一步”按钮,直到选择其中一个选项。我愿意使用 Javascript 和 JQuery。
这是 JSFiddle:http: //jsfiddle.net/547fx/
这是Javascript:
function tryToMakeLink() {
//get all selected radios
var q1 = document.querySelector('input[name="q1"]:checked');
//make sure the user has selected all 3
if (q1 == null) {
document.getElementById("linkDiv").innerHTML = "<input type=button
disabled=disabled value=Next>";
} else {
//now we know we have 3 radios, so get their values
q1 = q1.value;
//now check the values to display a different link for the desired configuration
if (q1 == "AT&T") {
document.getElementById("linkDiv").innerHTML = "<input type=button value=Next
onclick=\"window.location.href='http://google.com/';\">att 8gb black</input>";
} else if (q1 == "Other") {
document.getElementById("linkDiv").innerHTML = "<input type=button value=Next
onclick=\"window.location.href='http://yahoo.com/';\">other 8b white</input>";
} else if (q1 == "Unlocked") {
document.getElementById("linkDiv").innerHTML = "<input type=button value=Next
onclick=\"window.location.href='http://wepriceit.webs.com/';\">red</input>";
}
}
}
