validation

问题 I'm sorry if it's a duplicate of someone question. I didn't find a solution for my problem. Can anybody explain or give an example how to compare two fields in one form but in different form groups? Here is code snippet to see how my form and validator are look like: private createForm() { const testGroups = { groupOne: this.fb.group({ fieldOne: this.fb.control(null) }), groupsTwo: this.fb.group({ fieldTwo: this.fb.control(null, [this.matchValidator]) }) }; this.testForm = this.fb.group

问题 What is the best way in C++11 (ie. using C++11 techniques) to validate cin input? I've read lots of other answers (all involving cin.ignore, cin.clear, etc.), but those methods seem clumsy and result in lots of duplicated code. Edit: By 'validation', I mean that both well-formed input was provided, and that it satisfies some context-specific predicate. 回答1: I'm posting my attempt at a solution as an answer in the hopes that it is useful to somebody else. It is not necessary to specify a

问题 I got a new roo project off the ground successfully, but now I'm having a problem getting validation to work for a login page. It seems that the validator is choking before passing control to my controller. I am never given the opportunity to check the BindingResult. I've examined several similar questions here and on the web, and my code seems to conform with what they are doing. First the error I get when submitting the form (if i pass validation i get no error message). In this case i didn

问题 I am using twitter bootstrap for a site, and we use jquery.validate. I have a input element with button appended to input element. This is a required field within our js validation. The code is: <div class="controls"> <div class="input-append"> <input tabindex="1" name="url" class="input-large" id="url" type="text" placeholder="http://somewebsite.com" autocapitalize="off"> <button class="btn" type="button" name="attach" id="attach" />Fetch</button> </div> </div> Validation error class uses

问题 I have Joi schema and want to add a custom validator for validating data which isn't possible with default Joi validators. Currently, I'm using the version 16.1.7 of Joi const method = (value, helpers) => { // for example if the username value is (something) then it will throw an error with flowing message but it throws an error inside (value) object without error message. It should throw error inside the (error) object with a proper error message if (value === "something") { return new Error

问题 I want to validate image file uploads client side. T here will be server side validation, too, which is working already with image magick. I would like to reproduce this on the client side before uploading (since the files will be quite large and prerequisits for the image files are very restricted, it could save the user much pain if the validation takes place in the browser before the upload process) Allowed files would be: JPEG EPS TIFF I need to detect: Color Space (CMYK / RGB) Size

问题 I have a form element created with AngularJS with a submit button within it and I would like to put this button outside of this form. How can I do that with Angular and have my form still validated? e.g main html code: <div class="sd-chk-steps" ng-show="!step_03" ng-hide="step_03"> <!-- Panel Address --> <div id="sd-p-chk-1" class="large-8 columns sd-p-chk"> <div class="cover step_complete" ng-show="step_01" ng-hide="!step_01"> </div> <sd-panel-address > <!-- first form --> </sd-panel-address
