我有一个简单的表格，例如此演示.现在，我需要调用/检查表单是否已通过验证，或者以后不使用所选数据.例如在下面的例子中.我使用另一个ID为validateTrueorFalse的按钮来检查天气，验证结果为True还是False?

I have a simple Form like This Demo. Now what I need is to call/check if the form has been validated or not to use the selected data later on. For example in following example. I used another button with id validateTrueorFalse to check weather the result of validation is True or False?

Can you please help me to figure this out?

谢谢！

<form> <select id="mySelect"> <option value="1">Select From The List</option> <option value="2">First</option> <option value="3">Second</option> <option value="4">Third</option> <option value="5">Fourth</option> </select> <div id="error">Not selected!</div> <div id="valid">Validated!</div> <div id="result"></div> <br /> <button type="submit" class="btn btn-default">Validate</button> </form> <button class="validateTrueorFalse">Check If Validate</button> <div id="TruorFalese"></div>

推荐答案

您只需定义一个变量来确定验证失败或成功

You just define one variable to determine validate fail or successfully

例如:

$(document).ready(function () { var isValidate = false; $('form').submit( function(e) { var check=$('#mySelect').val() if ( check == '1' ) { $('#error').show(); $('#valid').hide(); isValidate = false; }else{ $('#error').hide(); $('#valid').show(); isValidate = true; } e.preventDefault(); }); $("#btnCheckValidated").click(function(){ content = isValidate ? "Form is validated successfully" : "Form is validated failed"; $("#valideeTruorFalese").html(content); }); });
