表单和 Bootstrap 模态

Question

我有这个表单可以让你选择或添加一个选项到下拉字段，问题是当你点击添加选项时，它调用了模式但它也提交了整个表单，但我把一个必需的输入字段上的标记，因此它不会真正通过表单，除非已完成

表格如下：

<div class="col-lg-12">
    <form action="<?php echo base_url(); ?>products/purchase"  role="form" accept-charset="utf-8" method="post">
    <div class="form-group">
        <div class="col-lg-12">
            <label class="control-label">Name</label>
            <input type="text" name="name" class="form-control inline" required>
        </div>
    </div>

    <div class="form-group">
        <div class="col-lg-10">
            <label class="control-label">Class</label>
            <div class="input-group">
                <select name="class_ID" class="form-control" required>
                <option value="">Select Class</option>
                <?php if(!empty($cls)){
                    if (is_array($cls)){                      
                        foreach ($cls as $row) {?>
                        <option value="<?php echo $row['class_id']?>"><?php echo $row['class_Name']; ?></option>
                        <?php }
                    }                           
                }

                else{   ?>
                <option value=""></option>
                <?php }?>
                </select>
                <span class="input-group-btn">
                    <button class="btn btn-theme" data-toggle="modal" data-target="#addClass"><i class="fa fa-plus"></i></button>
                </span>
            </div>
        </div>
    </div>  

    <div class="form-group">    
        <div class="col-lg-12 pull-right">
            <input type="submit" class="btn btn-success pull-right" value="Order" style="margin-left:5px;">
            </form> 
            <a href="<?php echo base_url()?>purchases" class="btn btn-default pull-right">Back</a>
        </div>
    </div>
</div>

和模态：

<div class="modal fade" id="addClass" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="vertical-alignment-helper">
        <div class="modal-dialog vertical-align-center">
            <div class="modal-dialog" role="document">
                <div class="modal-content">

                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <h4 class="modal-title">Add New Product Classification</h4>
                    </div>

                    <div class="modal-body">
                    <form action="<?php echo base_url(); ?>products/add_class" method="post" accept-charset="utf-8" role="form">
                        <div class="form-group">
                            <div class="col-lg-6">
                                <label for="class_Name">Classification Name</label>
                                <input type="text" name="class_Name" class="form-control">
                            </div>
                        </div>

                        <div class="form-group">
                            <div class="col-lg-3">
                                <label for="is_active">Enabled</label>
                                <select name="is_active" class="form-control">
                                    <option value="1">Yes</option>
                                    <option value="0">No</option>
                                </select>
                            </div>
                        </div>

                  </div>

                  <div class="modal-footer">
                      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                      <input type="submit" class="btn btn-success" value="ADD">
                      </form>
                  </div>
            </div>
        </div>
    </div>
</div>

Answer 1

可能是因为使用了两次class btn-success，你在打开模态时点击它，它在模型页脚的底部触发

Answer 2

平衡您的 html 标签即对于每个打开的标签，必须存在一个关闭的标签并且顺序也相同。

在您的模式中，您在 div 中打开您的表单标签，该标签在表单标签关闭之前关闭。某些浏览器可能会自动关闭此标记，因此点击您的提交按钮将传播到主表单。

改为

<div>
<form>
</form>
</div>

在 .modal-dialog 之前打开您的表单

Answer 3

改变

<button> to <a> or you can tell <button type="button"> that it's button and should only do what button supposed to do which is not to submit the form
