//获取模态 var modal=document.getElementById('myModal'); //获取打开模式对话框的按钮 var btn=document.getElementById(“myBtn”); //获取关闭模态的元素 var span=document.getElementsByClassName(“关闭”)[0]; //当用户单击该按钮时,打开模式对话框 btn.onclick=函数(){ modal.style.display=“块”; } //当用户单击(x)时,关闭模式对话框 span.onclick=函数(){ modal.style.display=“无”; } //当用户单击模式之外的任何位置时,将其关闭 window.onclick=函数(事件){ 如果(event.target==模态){ modal.style.display=“无”; } }
//为按钮添加差异id
开放式模式1
开放式模式2
//为模型添加差异id
//代码
//代码
var modal1=document.getElementById('myModal-1');
var modal2=document.getElementById('myModal-2');
myBtn-1.onclick=function(){
modal1.style.display=“块”;
}
myBtn-2.onclick=function(){
modal2.style.display=“块”;
}
//为按钮添加差异id
开放式模式1
开放式模式2
//为模型添加差异id

var modal2=document.getElementById('myModal-2');
myBtn-1.onclick=function(){
modal1.style.display=“块”;
}
myBtn-2.onclick=function(){
modal2.style.display=“块”;
}

我希望这将动态地解决您的问题。只需添加新按钮并将模式id传递到它的modalId属性中。它将完成其余工作。每个按钮不需要任何id
