<div class="container">

toggle="modal" data-target="#myModal">Open Modal</button>
<h3>Ex2</h3>
<button id="image2" type="button" class="btn btn-info btn-lg" data-
toggle="modal" data-target="#myModal">Open Modal</button>
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog" style="width:635px">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">

<h4 class="modal-title">Modal Header</h4>

<div class="modal-body">

<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script>
$(document).ready(function(){
var img = $(".modal-body img");
var imgSelected;
$("button").click(function(){
if($("button") === $("#image1")){
imgSelected = "002";
}
else{
imgSelected = "003";
}
img = $(".modal-body img");
img.attr("src", img.attr("src").replace("001", imgSelected));
});
});
</script>
</div>

您可使用：您可使用：

show.bs.modal：当调用Show实例方法时，此事件会立即发射。如果是由单击引发的，则单击元素可作为事件的相干属性属性可用。

为了更改图象源，您需要一个正则模式，而不是像002或003这样的固定模式，由于下次打开模式时，SRC值更改了。

因此，这种情况下，我的建议是：

$(document).ready(function(){
$('#myModal').on('show.bs.modal', function(e) {
var imgSelected;
if (e.relatedTarget.id == "image1"){
imgSelected = "002";
} else {
imgSelected = "003";
}
$(this).find(".modal-body img").attr('src', function(idx, attr) {
return attr.replace(/(\/)\d+(\.jpg)$/, '$1' + imgSelected + '$2');
})
$(this.dataset.target).modal('show');
});
});
