Question

This jquery_modal_confirm_dialogue is working after many experiments.
When our visitors agree to our Terms of Use, they are redirected to the product page products.html

I desperately need to set a cookie.
– if they do not agree, when they attempt to visit products.html, this
is not visible and displays the modal dialogue again

Could you please give me a hint?
(jquery 1.3.2.min.js)

This is my jqmodal.js

function confirm(msg,callback) {
  $('#confirm')
    .jqmShow()
    .find('p.jqmConfirmMsg')
      .html(msg)
    .end()
    .find(':submit:visible')
      .click(function(){
        if(this.value == 'yes')
          (typeof callback == 'string') ?
            window.location.href = callback :
            callback();
        $('#confirm').jqmHide();
      });
}


$().ready(function() {
  $('#confirm').jqm({overlay: 88, modal: true, trigger: false});

  // trigger a confirm whenever links of class alert are pressed.
  $('a.confirm').click(function() { 
    confirm('About to visit: '+this.href+' !',this.href); 
    return false;
  });
});// JavaScript Document

This is my index.html:

 <a href="http://products.html/" class="confirm">Products</a> 

    <div class="jqmConfirm" id="confirm">

    <div id="ex3b" class="jqmConfirmWindow">
        <div class="jqmConfirmTitle clearfix">
            <h1>Terms of Use</h1>
        </div>

        <div class="jqmConfirmContent">
        <p class="jqmConfirmMsg"></p>
            <p>Important legal information</p></div>

        <input type="submit" value="Decline" />
        <input type="submit" value="Proceed" />
        </div>
    </div>

It works, finally! I was missing the callback when the cookie exists and these tics ” around the value of the cookie. Here is how it looks like. Please, let me know if there is some obvious mistake. (many thanks for your support)

function confirm(msg,callback) {
  $('#confirm')
    .jqmShow()
    .find('p.jqmConfirmMsg')
      .html(msg)
    .end()
    .find(':submit:visible')
      .click(function(){
        if(this.value == 'Proceed'){
           $.cookie("agreed_to_terms", '1', { expires : 1, path: '/' }); //set cookie, expires in 365 days
           (typeof callback == 'string') ?
            window.location.href = callback :
            callback();
        }
        $('#confirm').jqmHide();
      });
}


$().ready(function() {
  $('#confirm').jqm({overlay: 88, modal: 'true', trigger: false});

  // trigger a confirm whenever links of class alert are pressed.
  $('a.confirm').click(function() { 
    if ($.cookie('agreed_to_terms') == '1'){window.location.href = callback =
            callback()
       //they already have cookie set
    }else{
       confirm('About to visit: '+this.href+' !',this.href); 
    }
    return false;
  });
