Call function after loading google custom search results?

Question

I basically need to run some jQuery code after the search results get rendered on my page. I can use either the v1 code:

<div id="cse" style="width: 100%;">Loading</div>
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<script type="text/javascript"> 
 google.load('search', '1', {language : 'en', style : google.loader.themes.V2_DEFAULT});
 google.setOnLoadCallback(function() {
var customSearchOptions = {};
var orderByOptions = {};
orderByOptions['keys'] = [{label: 'Relevance', key: ''},{label: 'Date', key: 'date'}];
customSearchOptions['enableOrderBy'] = true;
customSearchOptions['orderByOptions'] = orderByOptions;  var customSearchControl = new google.search.CustomSearchControl(
  'zzzzzzzzzzzz', customSearchOptions);
customSearchControl.setResultSetSize(google.search.Search.FILTERED_CSE_RESULTSET);
var options = new google.search.DrawOptions();
options.setAutoComplete(true);
customSearchControl.setAutoCompletionId('zzzzzz:zzzzzzz+qptype:3');
options.enableSearchResultsOnly(); 
customSearchControl.draw('cse', options);
function parseParamsFromUrl() {
  var params = {};
  var parts = window.location.search.substr(1).split('\x26');
  for (var i = 0; i < parts.length; i++) {
    var keyValuePair = parts[i].split('=');
    var key = decodeURIComponent(keyValuePair[0]);
    params[key] = keyValuePair[1] ?
        decodeURIComponent(keyValuePair[1].replace(/\+/g, ' ')) :
        keyValuePair[1];
  }
  return params;
}

var urlParams = parseParamsFromUrl();
var queryParamName = "q";
if (urlParams[queryParamName]) {
  customSearchControl.execute(urlParams[queryParamName]);
}
  }, true);
</script>

Or the v2 code:

<!-- Put the following javascript before the closing </head> tag. -->

<script>
    (function() {
var cx = 'xxxxxxxxx';
var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;
gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
    '//www.google.com/cse/cse.js?cx=' + cx;
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);
  })();
</script>

I've tried putting my function call in various places in the code but no avail.

I have a function that needs to dynamically set the height of the container the search results appear in, so once the results load I need to call it otherwise my page displays incorrectly.

Here is a link to their v2 API documentation: https://developers.google.com/custom-search/docs/element#cse-element and v1: https://developers.google.com/custom-search/docs/js/cselement-reference . I can't see anything where there is a callback upon search result rendering, only on initialization. Seems crazy though there isn't support for something like this.

Here is what I've tried with v2:

(function () {
        var cx = 'xxxxxxxxx';
        var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;

        gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
            '//www.google.com/cse/cse.js?cx=' + cx;
        gcse.onreadystatechange = gcse.onload = function () {
            console.log("executed");
            SetMainHeight(20);
        };
        var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);

    })();

The console never outputs "executed". Also I notice in my console I have the following error:

Unsafe JavaScript attempt to access frame with URL about:blank from frame with URL http://www.google.com/cse?q=test&client=google-coop&hl=en&r=s&cx=xxxxx…s1%2Csr1&rurl=http%3A%2F%2Flocalhost%3A58257%2FSearch%3Fq%3Dtest#slave-1-1. Domains, protocols and ports must match.

Not sure if that matters as the search function still works fine. I am testing this on localhost over http.

Answer 1

Unfortunately v2 doesn't have this ability, but in v1 you can use:

.setSearchCompleteCallback(object, method)

You can search for it on this page.

Answer 2

Previous solutions did not work for me, but here's what worked for me:

<script>
  (function() {

    window.__gcse = {
      callback: myCallback
    };

    function myCallback() {
       $('input.gsc-input').keyup(function(e) { if(e.keyCode == 13 || e.which == 13) {  console.log('enter pressed'); }});
      $('input.gsc-search-button').on('click', function(e) { console.log('clicked');});
    }
    var cx = '002806224466286757728:XXXXXXX';
    var gcse = document.createElement('script');
    gcse.type = 'text/javascript';
    gcse.async = false;
    gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
        '//www.google.com/cse/cse.js?cx=' + cx;
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(gcse, s);
  })();
</script>
<gcse:search></gcse:search>

Hope this helps

For v2, for example, try and set an onload handler to the gcse object (script) before inserting it in the DOM.

gcse.onreadystatechange = gcse.onload = function() {
  //execute my code
};

basically you end up with:

<!-- Put the following javascript before the closing </head> tag. -->

<script>
    (function() {
var cx = 'xxxxxxxxx';
var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;
gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
    '//www.google.com/cse/cse.js?cx=' + cx;
gcse.onreadystatechange = gcse.onload = function() {
  //execute your code here
};
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);
  })();
</script>
