我陷入了 laravel 项目的一个问题。我有一个票务页面，显示数据库车辆表中的巴士名称、巴士目的地、票值(value)。除此之外，还有一个用 JavaScript 制作的订票模板，用于计算数量和座位，并给出计数值和所选座位以及该页面。我想要做的是从 JavaScript 变量中获取这两个值，并将它们传递到订单表的数据库，就像显示的车辆表的其他值一样。我希望 var str 和 var rTotal 的值与使用 screen shot of front end 形式的隐藏字段发送的其他变量一起发送到数据库中

最佳答案
将两个隐藏字段添加到您的表单中:
<input type="hidden" id="str" name="str" value="">
<input type="hidden" id="rTotal" name="rTotal" value="">
然后在 getValue 和 getRealistic 函数中设置字段的值:
document.getElementById('str').value = str;
document.getElementById('rTotal').value = rTotal;
所以你最终会得到这样的函数:
function getValue() {
var checks = document.getElementsByClassName('checks');
var str = '';
for ( i = 0; i < 6; i++) {
if ( checks[i].checked === true ) {
str += checks[i].value + " ";
}
}
document.getElementById("lblRealfisti").innerHTML = str
document.getElementById('str').value = str;
}
function getRealistic() {
var rTotal = 0;
var selectedRealistic = document.forms["frmCareer"]["chkRealistic"];
for (var sel = 0; sel < selectedRealistic.length; sel++) {
if (selectedRealistic[sel].checked)
rTotal += getCareer[selectedRealistic[sel].value]
}
}
document.getElementById("lblRealistic").innerHTML = rTotal+ "/9 Checked"
document.getElementById('rTotal').value = rTotal;
}
