Bootstrap-Formz

Bootstrap form build helper.

This javascript class takes a simple object and builds Bootstrap form HTML.

• Required: the bootstrap CSS.
• Not required: no need to use jQuery or bootstrap JS.

Features:

• Basic fields: text, password, select, checkbox, radio, file, textarea, button, label
• Special fields: image, email, currency, inline, column
• Customizable column classes, init and ready functions and input classes
• Define your own field for more behaviors

Quick start

There is usually 2 columns: the label and the input field.

// create the form
var form = new BootstrapFormz({
	name: "myform",
	fields: [
		{ type: "text", value: "test", label: "Login", name: "login" },
		{ type: "password", label: "Password", name: "pwd" },
		{ type: "button", label: "Submit" }
	]
});

// just call render() on the Formz object and get the HTML
var html = form.render();

// Then just write it to the document or do whatever you want
document.write(html);

This will create an horizontal form with a login, password and button. There are many field types and many options you can use to customize your form.

For example, you can change the default column classes for the whole form or on a particular field.

var form = new BootstrapFormz({
	name: "myform",
	// set the default column setting for the fields:
	columns: ["col-sm-5", "col-sm-7"], 
	fields: [
		{
			type: "text",
			value: "test",
			label: "Login"
		},
		{
			type: "button",
			label: "Submit", 
			// set the column setting for this fields:
			columns: "col-sm-12"
		}
	]
});
document.write(form.render());

Initialization

Each field have a init function that is called when the field is initiated. This function would normally set the default values of variables if not set. But if you change the function, it can do other things. When the init function is called, the form HTML is generating so the input is not yet on the page.

var form = new BootstrapFormz({
	fields: [
		{
			type: "text",
			label: "Your text",
			name: "mytext",
			value: "",
			init: function() {
				// this.super.init();
				alert('text input initiated');
			}
		}
	]
});
document.write(form.render());

Ready

Each field have a ready function that is called when DOM is ready or the formz.ready() function is called. If you ouput the form on your document, the function can access the input if you

var form = new BootstrapFormz({
	fields: [
		{
			type: "text",
			label: "Your text",
			name: "mytext",
			value: "",
			init: function() {
				// this.super.init();
				alert('text input initiated');
			}
		}
	]
});
document.write(form.render());

Image full preview

You can replace the full preview open function to put your own.

var form = new BootstrapFormz({
	fields: [
		{
			type: "image",
			label: "An image",
			name: "myimage",
			url: "image/yourmom.png",
			preview_click: function() {
				alert('custom full image preview');
			}
		}
	]
});
document.write(form.render());
