这是我的剧本:
function myFunction() {
var x = document.getElementById("mySelect").value;
var xtest = x.split("|");
x = xtest[1];
document.getElementById("demo").innerHTML = x;
var text = $('#demo').html();
$('#texted').val(text);
}
$(document).ready(function() {
myFunction();
$("#mySelect").change(function() {
myFunction();
sum();
});
sum();
$("#num1, #texted").on("keydown keyup", function() {
sum();
});
$("#num1").mouseup(function() {
sum();
});
});
function sum() {
var num1;
num1 = document.getElementById('num1').value;
document.getElementById('sum').value = num1;
var texted = document.getElementById('texted').value;
}
这是我从哪里获得值类型(文本)
echo"<select name='id_type' id='mySelect' onchange='myFunction()' class='form-control select' data-live-search='true'>";
foreach($data as $r){
echo"<option value=".$r['id_type']."|".$r['libelle'].">".$r['libelle']."</option>";
}
echo"</select>";
<p id="demo"></p>
这是我想要放置我选择的值的地方
echo"<select name='echange' id='texted' class='form-control select' data-live-search='true'>";
foreach($data as $r){
echo"<option value=".$r['id_annee'].">".$r['libelle']."</option>";
}
echo"</select>";
P.S此方法的目的是使在上一次选择中找到特定数据变得容易

使用PHP构建每个列表都很好,但您肯定希望使用JavaScript来操作每个列表的值。例如(我将在这里使用直接JS)你可以做这样的事情
list1 = document.getElementById("mySelect");
list2 = document.getElementById("texted");
list1.onblur = function() {
list2.value = list1.options[list1.selectedIndex].value;
//add option
var opt = document.createElement('option');
opt.value = list1.options[list1.selectedIndex].value;
opt.innerHTML = list1.options[list1.selectedIndex].value;
list2.appendChild(opt);
}
