【问题描述】：

我正在使用 Bootstrap (plugin): validator.js v0.11.9 bootstrap validator 在 Python 项目中进行字段验证（Python 3.6 版和 Django 1.11 版） .在按钮 click 上，我使用 jquery 在表单中添加了几个字段 -

jQuery :

 $("#button1Id").click(function()
    $("#divInsideFormId").append('filed1-selectoption, field2-datepicker, field3-textbox');             
);

根据文档validator fields

默认情况下，验证器只会验证插件初始化时存在的字段。如果您的表单有一组动态字段，您需要调用 $(...).validator('update') 通知插件要验证的字段集已更改。

我尝试了以下 -

$("#button1Id").click(function()
    $("#divInsideFormId").append('filed1-selectoption, field2-datepicker, field3-textbox');
    $("#formId").validator('update');           
);

这不起作用。我也试过-$("#divInsideFormId").append(...).validator('update');

即使这样也行不通。

谁能建议我的代码有什么问题或者我遗漏了什么？

【参考方案1】：

这是一个有效的 sn-p：

$("#button1Id").click(function()

    var html = '<label for="inputName" class="control-label">New numeric field</label><input type="number" class="form-control" id="inputNum" placeholder="new num field" required>';
    $("#divInsideFormId").append(html);
    $("#formId").validator('update');           
);
