如果文本框验证失败，如何在该文本框上放置引导工具提示

How to put bootstrap tooltip on textbox if validation fails for that textbox?

本文关键字：文本 工具提示 失败 验证 如果      更新时间：2023-09-26

如果没有值（空），我想对文本框执行验证。

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;
}

我已经检查了引导工具提示的例子，甚至尝试过，但它不起作用。

那么，如何使用引导工具提示来验证我的文本框呢？？

以下是如何使用Bootstrap&jQuery，但您也应该了解如何将验证组合在一起，因为有各种方法；这个工具提示示例取自

$("#valForm").validate({
  showErrors: function(errorMap, errorList) {
    // Clean up any tooltips for valid elements
    $.each(this.validElements(), function(index, element) {
      var $element = $(element);
      $element.data("title", "") // Clear the title - there is no error associated anymore
        .removeClass("error")
        .tooltip("destroy");
    });
    // Create new tooltips for invalid elements
    $.each(errorList, function(index, error) {
      var $element = $(error.element);
      $element.tooltip("destroy") // Destroy any pre-existing tooltip so we can repopulate with new tooltip content
        .data("title", error.message)
        .addClass("error")
        .tooltip(); // Create a new tooltip based on the error messsage we just set in the title
    });
  },
  submitHandler: function(form) {
    alert("This is a valid form!");
  }
});
$('#reset').click(function() {
  var validator = $("#valForm").validate();
  validator.resetForm();
});
body {
  background: rgba(255, 255, 255, 0.45);
}
.wrapper {
  padding-top: 75px;
}
#valForm input {
  width: 100%;

#valForm .error {

#valForm .tooltip > .tooltip-inner {

首先，您应该包含Bootstrap Tooltip插件来调用Tooltip（）。

有一个可用于引导的直接插件，请尝试使用此引导验证工具提示。
