− Table of content
The html generator relies on jquery. Specifically some fields and its javascipt depend heavily on it.
It is the default jelix generator for jForms. html is the name to give to {form} and {formfull} template plugins, if needed.
Options ¶
Options you can give in an array as the fifth argument of {form} and {formfull} :
errorDecorator: the name of the javascript object which handles error messagesmethod: the HTTP method ('get' or 'post'). By default: 'post'.
Usefull CSS classes ¶

Customizing messages display ¶
jForms deals with two types of messages :
- error messages generated by form checking
- help messages accessible through interrogative point
Error messages are displayed defaultly on the top of the form. You can customize this behaviour. Transmit your own javascript messages display function to {form} or {formfull} plugins.
Error messages display ¶
To customize display of error messages, you shall define a javascript object implementing 3 methods:
- start, called when checking process starts.
- addError, called when an error is found. it receives a
jFormsControlargument, which contains infos about the erroneous control, and an error code. the latter equals 1 if user has not edited a required control, 2 if its content is invalid. - end, called when checking process ends.
You're obviously free to do whatever you need/want in those methods. As for example, you could add the error messages to an error lists ( <ul> located in your html page):
function MyErrorDecorator(){
}
MyErrorDecorator.prototype = {
start : function(){
},
addError : function(control, messageType){
var message='';
if(messageType == 1){
message = control.errRequired;
}else if(messageType == 2){
message = control.errInvalid;
}else{
message = "Error on '"+control.label+"' field";
}
var item = document.createElement("li");
item.appendChild(document.createTextNode(message));
document.getElementById("errors").appendChild(item);
},
end : function(){
}
}
Then, declare your MyErrorDecorator object in the options parameters of form or formfull:
{form $form, 'mymodule~default:save', array(), 'html', array("errorDecorator"=>"MyErrorDecorator")}
...
{/form}
Details about jFormsControl object passed to addError (named control above), and its properties:
- name : control or field name
- label : its label
- datatype : its data type (type attribute in your XML file)
- required : boolean, true if required
- readonly : boolean, true if readonly
- errInvalid : invalid error message defined in your XML file
- errRequired : required error message defined in your XML file
- help : help message defined in your XML file
Help messages display ¶
In previous versions, Help messages were displayed by a javascript object in the same manner of errors, but it is not the case in jelix 1.2 and above. Help messages are displayed in a CSS help balloon when the mouse is hover the help image.
If you want to customize them, you need to provide your own CSS.
jQuery and your application ¶
HTML generator forces jQuery inclusion on every HTML response including a jForm. Thus, if you already link to jQuery script elsewhere in your appplication, such as in your common response, you should take care to include the very same script. Otherwise, your user will download it twice.
Example in a common respsonse :
$this->addJSLink(jApp::config()->urlengine['jelixWWWPath'].'jquery/jquery.js');
