optikalefx Posted December 17, 2007 Share Posted December 17, 2007 I have a variable 'i' that is changed by functions. And i want the functions to act based on those changes. I.E a global variable. But i cant get it to work. 'i' doesnt change outside the function <html> <head> <script type="text/javascript"> var i = 3; function reti(i) { alert(i); } function addField(i) { i++; document.getElementById('fields').innerHTML += "<span id='db" + i + "'>Data field " + i + ": <input type='text' name='db" + i + "'><br>\n"; return i; } function delField(i) { document.getElementById('db'+i).innerHTML = ""; return i--; } function liveSearch() { if(document.xmlCreator.livesearch.checked == true) { document.getElementById('liveSearches').innerHTML += "Which field to Display?: <input type'text' size='2' name='ls'><br>\n"; } else { document.getElementById('liveSearches').innerHTML = ""; } } </script> </head> <form name="xmlCreator"> Database name: <input type="text" name="database_name"><br> <div id="fields"> <span id="db1">Data field 1: <input type="text" name="db1"><br> <span id="db2">Data field 2: <input type="text" name="db2"><br> <span id="db3">Data field 3: <input type="text" name="db3"><br> </div> <input type="button" onClick="reti(i);" value="What is i"> <input type="button" onClick="i = addField(i);" value="Add a field"> <input type="button" onClick="i = delField(i);" value="Delete a field"><br> Live Search? <input type="checkbox" name="livesearch" onchange="liveSearch();"><br> <div id="liveSearches"> </div> </form> </html> i can add fields fine, and i can delete 1 field. But i cant delete more than one. and then after you delete one, i is the same as it was, it didnt decrement so the numbers are off.

phpQuestioner Posted December 17, 2007 Share Posted December 17, 2007 look into addChild(), removeChild(), and appendChild() - that's you best bet for doing something like this.

optikalefx Posted December 17, 2007 Author Share Posted December 17, 2007 i know i have to use those when i make the xml file, but before that i want the user to enter values, so i have the text boxes dynamically show up so the user can enter the name of the nodes.

markjoe Posted December 20, 2007 Share Posted December 20, 2007 (non-expert alert) What about making it a (pseudo)class? I made my first one only a few days ago. I have had global variable problems like this in the past. I have not, however, had any issue refering to "this.variable" in a method. Or, sometimes I fall back on a hidden input in palce of a global variable, ugly way of doing things, but it works.
