javascript - 一页上的多个表单模式

Question

我需要有关 javascript 的帮助。我正在尝试使用多种形式在模式中显示动态名称。这是我所拥有的，但上面写着“你确定要删除鲍勃吗？”但如果我点击删除汤姆按钮，我希望它显示汤姆。

表格:

<form role="form" id="formfield" action="<?=$_SERVER['PHP_SELF']?>" method="post">
<input type="hidden" name="username" id="username" value="bob" /> 
<input type="hidden" name="delete_id" id="delete_id" value="45" /> 
<button type="button" name="btn" value="Delete" id="submitBtn" data-toggle="modal" data-target="#confirm-delete" class="btn btn-xs btn-danger tooltip-error no-border" style="padding:5px; width:30px; height:30px;" /><i class="fa fa-trash-o bigger-120"></i></button>
</form>

<form role="form" id="formfield" action="<?=$_SERVER['PHP_SELF']?>" method="post">
<input type="hidden" name="username" id="username" value="tom" /> 
<input type="hidden" name="delete_id" id="delete_id" value="48" /> 
<button type="button" name="btn" value="Delete" id="submitBtn" data-    toggle="modal" data-target="#confirm-delete" class="btn btn-xs btn-danger tooltip-error no-border" style="padding:5px; width:30px; height:30px;" /><i class="fa fa-trash-o bigger-120"></i></button>
</form>

模态:

<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                Confirm Submit
            </div>
            <div class="modal-body">
                Are you sure you want to delete <span id="deletename_id">?
            </div>
            <div class="modal-footer">
                <button type="button" id="cancel" class="btn btn-default success" data-dismiss="modal">Cancel</button>
                <a href="#" id="delete" class="btn btn-danger success">Delete</a>
            </div>
        </div>
    </div>
</div>

Javascript:

<script>
$('#submitBtn').click(function() {
     $('#deletename_id').text($('#username').val());
});

$('#delete').click(function(){
    $('#formfield').submit();
});
</script>

Answer 1

首先，您需要使用submitBtn 类，因为您有两个具有相同id 的元素。 请试试这个:

$('.submitBtn').click(function() {
    $('#deletename_id').text($(this).parents('form').find('input').eq(0).val());
});

另一种方法是使用这个方法:

$('#deletename_id').text($(this).parents('form').find('#username').val());

在这两种方法中，您都需要找到包含单击的按钮的表单，然后，您需要找到输入。

$('.submitBtn').click(function() {           
  $('#deletename_id').text($(this).parents('form').find('input').eq(0).val());
});

$('#delete').click(function(){
    $('#formfield').submit();
});
