Angular implements automatic form layout and angularform Layout

This article provides an example of how Angular implements automatic form layout and shares it with you for your reference. The specific content is as follows:

:

Code:

1. formlayoutCtrl. js

'Use strict '; sxlcApp. controller ('formlayoutctrl ', [' $ scope ',' $ filter', '$ http', function ($ scope, $ filter, $ http) {$ scope. title = 'form layout '; $ scope. dataParamsUrl = '. /php/formlayout. json '; $ scope. resetForm = function (num) {console. log (num)}]);

2. formlayout.html

<Div class = "container" ng-controller = "formlayoutCtrl"> <span >{{ title }}</span> <form class = "form-horizontal" style = "width: 400px; "name =" formlayout "w5c-form-validate =" validateOptions "novalidate> <form-layout url =" dataParamsUrl "> </form-layout> <button type =" submit "class =" btn btn-sm btn-info "> submit </button> <button type =" reset "class =" btn-sm btn-danger "ng-click =" resetForm () "> Reset </button> </form> </div>

3. formlayout.html

<Div class = "container" ng-controller = "formlayoutCtrl"> <span >{{ title }}</span> <form class = "form-horizontal" style = "width: 400px; "name =" formlayout "w5c-form-validate =" validateOptions "novalidate> <form-layout url =" dataParamsUrl "> </form-layout> <button type =" submit "class =" btn btn-sm btn-info "> submit </button> <button type =" reset "class =" btn-sm btn-danger "ng-click =" resetForm () "> Reset </button> </form> </div>

4. formlayoutdirective. js
