init status:
After clicking "+":
After verification:
Knowledge points:
1 First go to the official website to download: formvalidation.io/
2. Import the file. I won’t go into details about the precautions. I have already mentioned them in the remote verification article.
3 Keywords used: addField, removeField, different
4 Note that the names of the examples on the official website are different. I'm a bit lazy here. And when the project is ajaxed, the form is not used for submission, but is submitted as json by itself, so the names of x and y have the same name.
Good start:
First of all, there must be a "+" in the html, marked as addPos, and then there must be a "-" marked as "removPos,
<p id="posXY" class=" panel panel-default "> <!-- 添加--> <p class="panel-heading" >设置车库xy坐标</p> <p class="addPos form-group"> <p class="col-lg-4 col-sm-4 col-xs-4" > <input type="text" class="form-control text-left" name="garageNo" placeholder="停车库" style="min-width: 150px"/> </p> <p class="col-lg-3 col-sm-3 col-xs-3" > <input type="text" class="form-control" name="posX" placeholder="X"/> </p> <p class="col-lg-3 col-sm-3 col-xs-3" > <input type="text" class="form-control" name="posY" placeholder="Y"/> </p> <p class="col-lg-2 col-sm-2 col-xs-2" > <button type="button" class="btn btn-default addButtonPos"><i class="glyphicon glyphicon-plus"></i></button> </p> </p> <!-- 删除 --> <p class="removPos form-group hide" id="posTemplate"> <p class="col-lg-4 col-sm-4 col-xs-4" > <input type="text" class="form-control text-left" name="garageNo" placeholder="停车库" style="min-width: 150px"/> </p> <p class="col-lg-3 col-sm-3 col-xs-3" > <input type="text" class="form-control" name="posX" placeholder="X"/> </p> <p class="col-lg-3 col-sm-3 col-xs-3" > <input type="text" class="form-control" name="posY" placeholder="Y"/> </p> <p class="col-lg-2 col-sm-2 col-xs-2" > <button type="button" class="btn btn-default removeButtonPos"><i class="glyphicon glyphicon-minus"></i></button> </p> </p> </p>
Then Here is a js:
/** * pos添加 * @param $that */ function addButtonPosClick($that){ var panelId = $that.parents(".topTemplate").attr("id"); var $form=$('#'+panelId+"form") // defaultPanel(panelId) var bookIndex=typeObj[panelId]++; console.log(panelId,bookIndex) var $template = $('#'+panelId+' #posTemplate'), $clone =$template .clone() .removeClass('hide') .removeAttr('id') .attr('step',bookIndex) .insertBefore($template); // Update the name attributes $clone .find('[name="garageNo"]').attr({"step":bookIndex,"name":"garageNo"+bookIndex}) .click(function(){ clickBindGarageNo(panelId,bookIndex) }).end() .find('[name="posX"]').attr("step",bookIndex).end() .find('[name="posY"]').attr("step",bookIndex).end() // Add new fields // Note that we also pass the validator rules for new field as the third parameter // $('#defaultForm') // gFieldArr.push(panelId+'[' + bookIndex + '].garageNo') $form .formValidation('addField', "garageNo"+bookIndex, formObj.sameAs(false)) .formValidation('addField', 'posX', myPosXY) .formValidation('addField', 'posY', myPosXY) } function myFormValidation($form){ // var $form=$("#"+$panelId+"form") $form .formValidation({ framework: 'bootstrap', locale: 'zh_CN', message: '值无效', icon: { valid: 'glyphicon glyphicon-ok', invalid: 'glyphicon glyphicon-remove', validating: 'glyphicon glyphicon-refresh' }, fields: { myimg:{ validators: { notEmpty: { message: '请选择一个文件上传' }, file: { extension: 'jpeg,jpg,png', type: 'image/jpeg,image/png', maxSize: 1*1024 * 1024, message: '该文件必须为jpeg,jpg,png格式和必须不超过1MB的大小' } } } } }) .on('click', '.addButtonPos', function() { addButtonPosClick($(this)) }) //Remove button click handler .on('click', '.removeButtonPos', function() { var $that = $(this) var panelId = $that.parents(".topTemplate").attr("id"); // defaultPanel(panelId) var $row = $(this).parents('.form-group'), index = $row.attr('step'); // var myname='[' +index + ']' var bookIndex= typeObj[panelId]--; // $('#defaultForm') $form .formValidation('removeField', $row.find('[name="garageNo'+bookIndex+'"]')) .formValidation('removeField', $row.find('[name="posX"]')) .formValidation('removeField', $row.find('[name="posY"]')) // Remove element containing the fields $row.remove(); })
Because my project has multiple form submissions, but the business is similar, I use these functions
For example: var form=("#" +panelId+”form”)
Use panelId to distinguish multiple forms.
As mentioned above, the names of x and y are the same, but if you are careful, you will find that garageNo has a different name. . Bookindex was added later, why.
Because of business requirements. For example, the identity number of each person cannot be the same. The tablemates can be both female and 18 years old...
The keywords removeField and addField
## cannot be the same. How to do it. Please see below:var differentValid= function(diffstr){ var vv={ validators: { different: { field: diffstr, message: '不能有相同的停车库' } } } return vv }
clickBindGarageNo(panelId,idx){ $form.formValidation('addField', "garageNo"+idx, differentValid(diffArr.toString())) var fv =$form.data('formValidation'); fv.validate(); }
String of nameFor example: there are 3 entries, idx=1 and the focus is on 1. Then diffArr=["garageNo0","garageNo2",]
$form.formValidation('revalidateField', "field");
$btn.click(function(){ //.... retrun false; )}
