我的代碼正常工作,我只需要收音機未檢查然後按繼續,在問題結束時它將顯示require
。我不知道如何使用JavaScript來做到這一點。JavaScript在末尾添加css文本
我也曾嘗試questions[j].className = "highlight";
HTML:
<form>
<div class="str_Radio">
<p> 1. </p>
<label> I cant make this work. </label>
<div class="strQuestion">
<input type="radio" name="Dq[1]" value="1">1
<input type="radio" name="Dq[1]" value="2">2
<input type="radio" name="Dq[1]" value="3">3
<input type="radio" name="Dq[1]" value="4">4
<input type="radio" name="Dq[1]" value="5">5
<input type="radio" name="Dq[1]" value="6">6
<input type="radio" name="Dq[1]" value="7">7
<input type="radio" name="Dq[1]" value="8">8
<input type="radio" name="Dq[1]" value="9">9
<input type="radio" name="Dq[1]" value="10">10
</div>
</div><!-- 11 -->
<div class="str_Radio">
<p> 2. </p>
<label> this will not work 2. </label>
<div class="strQuestion">
<input type="radio" name="iq[1]" value="1">1
<input type="radio" name="iq[1]" value="2">2
<input type="radio" name="iq[1]" value="3">3
<input type="radio" name="iq[1]" value="4">4
<input type="radio" name="iq[1]" value="5">5
<input type="radio" name="iq[1]" value="6">6
<input type="radio" name="iq[1]" value="7">7
<input type="radio" name="iq[1]" value="8">8
<input type="radio" name="iq[1]" value="9">9
<input type="radio" name="iq[1]" value="10">10
</div>
</div><!-- 22 -->
<button id="link" name="data" type="button" onclick="return validateForm('strQuestion');">Continue</button>
</form>
CSS:
.highlight{
content: "*";
color:red;
}
的JavaScript:
function validateForm(cname) {
var questions = document.getElementsByClassName(cname);
formValid = true;
for(var j=0; j<questions.length; j++) {
if(!isOneInputChecked(questions[j], "radio")) {
formValid = false;
questions[j].style.border = "2px solid red";
// i use loop to target each question here i change css.
}
}
return formValid;
}
function isOneInputChecked(sel) {
var inputs = sel.getElementsByTagName('input');
for (var k=0; k<inputs.length; k++) {
if(inputs[k].checked)
return true;
}
// End of the loop, return false
return false;
}
和我的代碼返回秀真的werid,它不會針對那些不再被檢查的人。我要如何完成這個?謝謝。

可以嘗試重新之前粘貼我的代碼?一旦我有2個問題,它不會再工作了。 – user3233074 2015-01-21 05:16:53
什麼不起作用?請確保您包含問題[j] .className =「highlight」,它不在您最初發布的代碼中。它的工作原理是 – Mike 2015-01-21 05:22:16
