Javascript to Execute Before Post

Hi,

I'd like some javascript to execute when a user clicks "post" when either begining a thread or replying. Basically for many complicated reasons (too much detail to provide in this post) we're needing to check the post for a certain character set and if the post or title contains this character set we don't want to allow the user to post. I know the Lithium out of the box content filters do forms of this, but for numerous reasons that will not meet our needs. Does anyone know how I can make this javascript execute upon the "post" action? I'm unsure which API call is best.

 

Thanks,

Jordan

    Hi Jordan

     

    You can use below jquery code to prevent from submition of form;

     

    Replace "#confirmForm" with class or id of the submit button.

    Replace "#FieldName" with class or id of the field you are using.

     

    $('#confirmForm').submit(function(ev){
    var CharCount = $('#FieldName').val().length;
    if (CharCount > 50) {
    return false;
    }
    });

    Hi,

     

    The following jquery code might fullfill your needs. 

     

    $('.lia-button-Submit-action').bind('click', function(e) {

    /* perform your validation here */
    var subject = $(".lia-subject");
    if(subject.value.match(/* characters to check */))
    {
    e.preventDefault();
    alert(/* alert user for wrong characters */)
    }else {
    return true;
    }
    };

     

    I have given example to check subject after user click Post button.
