我有一个带有多个按钮的while循环,它们是这样的:
<button onclick="confirmDelete()" value="<?php echo $game['id'];?>" name="deleteButton">Delete </button>
接下来是以下确认消息:
<script>
function confirmDelete() {
var r = confirm(" **HERE I WANT THE ID TO START WITH** ");
if (r == true) {
// delete
} else {
// cancel
}
}
</script>
每个按钮都有自己的值,但现在我想在我的javascript中点击该按钮时的值。我试过很多东西,但不能让它起作用。

如果有人能告诉我一个更好/更简单的方法,欢迎您告诉我

将您的函数与this
参数一起使用,即:
<button onclick="confirmDelete(this)" id="myButton" value="someId" name="deleteButton">Delete </button>
<script>
function confirmDelete(elem) {
var r = confirm(" **HERE I WANT THE ID TO START WITH** ");
var theValue = elem.value; //someId
var theId = elem.id; //myButton
if (theValue == "True") {
alert("True")
} else {
alert("False")
}
}
</script>

将游戏ID作为参数
传递给confirmDelete函数<button onclick="confirmDelete(<?php echo $game['id'];?>)" name="deleteButton">Delete </button>
<script>
function confirmDelete(id) {
var r = confirm(id);
if (r == true) {
// delete
} else {
// cancel
}
}
</script>
