    copied!<p>I am looking for a script that calls for a JavaScript function automatically when reaching the maxlength of a text field.</p> <p>I tried to modify this piece of Script which I found here <a href="https://stackoverflow.com/questions/11801672/ajax-call-after-x-characters">ajax call after x characters</a></p> <pre><code>$("input#zipcode").live("keyup", function( event ){ if(this.value.length == this.getAttribute('maxlength')) { if(!$(this).data('triggered')) { // set the 'triggered' data attribute to true $(this).data('triggered',true); if ($(this).valid() == true ) { loadXMLDoc(); } } } else { $(this).data('triggered',false); } }); </code></pre> <p>This is the part of code containing the loadXMLDoc part:</p> <pre><code>function loadXMLDoc() { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4) { document.getElementById("state_insert").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","state_insert.asp?zipcode="+document.getElementById('zipcode').value,true); xmlhttp.send(); } </code></pre> <p>When the maxlength is reached, I want it to call for a "LoadXMLDoc" function which requires no additional parameters to be passed on.</p> <p>At the moment I have it set to onblur="LoadXMLDoc()" Like this:</p> <pre>[input name='zipcode' type='text' class="form_elements" id='zipcode' tabindex='11' autocomplete='off' onchange="this.value=extractNumeric(this.value)" onkeypress="return isNumericKey(event)" value='' size="4" maxlength="5" onblur="loadXMLDoc()" /]</pre> <p>I used the [ and ] because &lt; and > are not allowed.</p> <p>in the text field properties, but I would like that it loads as soon as the 5 digits of the Zip Code have been entered.</p> <p>Thanks in advance :)</p> <pre><code>Robert. </code></pre>
