Question

如果没有值（空），我想在文本框上执行验证。

如果验证失败，我想在文本框上显示工具提示。

这是我的文本框：

<input type="text"  id="txtNo1" />
<input type="text"  id="txtNo2" />
<input type="text"  id="txtNo3" />

<input type="button" onclick="return ManipulateValue();">



function ManipulateValue() {
        var isValid = true;
         $('#txtNo1,#txtNo2,#txtNo3').each(function () {
            if ($.trim($(this).val()) == '') {
                isValid = false;
                $(this).css({
                    "border": "1px solid red",
                    "background": "#FFCECE"
                });
                $(this).tooltip('show'); //not working
            }
            else {
                $(this).css({
                    "border": "",
                    "background": ""
                });
                //$(this).tooltip('hide'); //not working
            }
        });
        if (isValid == false) {
            return false;
        }
       //ajax call to my controller method
     return true;
}

我已经检查了bootstrap工具提示的示例，甚至尝试了它但它无法正常工作。

那么如何使用bootstrap工具提示来验证我的文本框？

首先，您应该包含Bootstrap Tooltip plugin来调用工具提示（）。

有一个可用于bootstrap的直接插件，请尝试使用此Bootstrap Validation Tooltip.

如果该文本框的验证失败，如何在文本框上放置bootstrap工具提示？
