Question

我有这个表格

对于明星有5个图像，onclick设置为functionstar1，functionstar2等...更改图像的url（有2个url star1.png（黄色）和star2.png（白色））。这是控制星星的脚本：

<script>function functionStar1() {
document.getElementById('star1').src = "star1.png";
document.getElementById('star2').src = "star0.png";
document.getElementById('star3').src = "star0.png";
document.getElementById('star4').src = "star0.png";
document.getElementById('star5').src = "star0.png";
}
function functionStar2() {
document.getElementById('star1').src = "star1.png";
document.getElementById('star2').src = "star1.png";
document.getElementById('star3').src = "star0.png";
document.getElementById('star4').src = "star0.png";
document.getElementById('star5').src = "star0.png";
}
function functionStar3() {
document.getElementById('star1').src = "star1.png";
document.getElementById('star2').src = "star1.png";
document.getElementById('star3').src = "star1.png";
document.getElementById('star4').src = "star0.png";
document.getElementById('star5').src = "star0.png";
}
function functionStar4() {
document.getElementById('star1').src = "star1.png";
document.getElementById('star2').src = "star1.png";
document.getElementById('star3').src = "star1.png";
document.getElementById('star4').src = "star1.png";
document.getElementById('star5').src = "star0.png";
}
function functionStar5() {
document.getElementById('star1').src = "star1.png";
document.getElementById('star2').src = "star1.png";
document.getElementById('star3').src = "star1.png";
document.getElementById('star4').src = "star1.png";
document.getElementById('star5').src = "star1.png";
}</script>

我使用javascript发送信息，因为我需要使用此脚本的星号网址：

<script>var password;
var titolo;
var feedback;
var valutazione;
var url;
function open(){
password = document.getElementById("password").value;
titolo = document.getElementById("titolo").value;
feedback = document.getElementById("feedback").value;
if (document.getElementById('star5').src == 'http://www.***.eu/star1.png') {
    valutazione = 'Eccellente';
} else if (document.getElementById('star4').src ==  
'http://www.***.eu/star1.png'){
    valutazione = 'Discreto';
}else if (document.getElementById('star3').src ==     
'http://www.***.eu/star1.png'){
    valutazione = 'Sufficiente';
}else if (document.getElementById('star2').src ==  
'http://www.***.eu/star1.png'){
    valutazione = 'Non sufficiente';
} else {
    valutazione = 'Pessimo';
}
url = 'http://www.***.eu/input.php?password=' + password + '&titolo=' +   
titolo + '&feedback=' + feedback + '&valutazione=' + valutazione;
document.getElementById("buttonhref").href = url;
}
setInterval(open, 10)</script>

问题在于它发送的<textarea>文字没有\n。有没有办法用\n使用javascript或更好的方式来获取文本有没有办法在没有javascript的情况下发送星图的网址？

Answer 1

如果您不想使用Javascript发送数据，则可以设置一个隐藏值，该值随着星号的数量而更新，然后在表单提交后进行处理。

<input type="hidden" name="stars" value="5" id="stars-val" />

<script>
  function updateStarValue(starNum){ // star num is 1,2,3,4,5
  document.getElementByID("stars-val").val = starNum;
  }
</script>

然后在每个星星上onclick=updateStarValue(2)等

否则，使用preg_replace将换行符更改为

发送反馈表
