JavaScript - Anyone Wants To Talk About An Architecture Problem?
I'm working on a webmail application, and I'm building all the logic process in the client side, the scripts on the backend only gives me xml and I process it with jquery to build the entire interface: list folders, list messages, send messages, etc.
When the application loads it download 290kb (uncompressed) of js, css and xml. The application must grow with the time with new features. One of my coworkers suggested me to move the logic from client-side to the server-side (in ruby) to avoid slowness on the client and to make easier to implement these new features. Any toughts about it? thanks. Similar TutorialsHi can Javascript talk to the flash plugin to access the microphone functionality? if so how can i do this? Hi pals, I am really tired in this problem of event keyup. I given same in my keyup function like: $(document).ready(function () { alert("GGG"+parseInt(jQuery.browser.version)); //To display test value working $("#find_text").keyup(function(e) { if(e.which == 13) { alert('Enter key was pressed'); //enter Here alert("FFF"+parseInt(jQuery.browser.version)); //Here got Error } }); }); I got Error : jQuery is not defined alert("FFF"+parseInt(jQuery.browser.version)); I use keycode,which , but no help, It's Work nicely in Chrome Browser but not in FF. Please give a Solution reply ASAP, I am really Tired.The code enter the Condition But that jQuery part make error. Thankfully Anes P.A Hey guys! :-) How do i translate this javascript sentense in to "real working" javascript. PHP Code: if(a1 "its a box/this is just for info" = got a value written){ c1 also a box = disabled; } How do i write this so it works? My first thought was: PHP Code: if(document.GetElementById(a1).value = true){ document.GetElementById(c1).disabled = true; } But cant get it working - is there somebody there could help me? :-) //Morten Larsen // Denmark. I really don't even know if I'm posting this question in the right section. I am using javascript to make a drop-down menu for a website. I really don't have any experience with javascript. The problem I'm having is that when I go to the page, the drop down menu is already dropped down. If you then hover over it, it pulls up and then hover over it again and it drops back down. It works fine after the initial glitch. Didn't know if anyone had run into this problem or if I'm just being stupid, here is the code that I'm using. Thanks in advance for any help. <a href="/mainpage.html" onMouseOver="show()" onMouseOut="hide()" ><img src="pic.png" border="0" width="90" height="24"></a></br> <div id="div1"><a href="/notherpage.html" onMouseOver="show()" onMouseOut="hide()" ><img src="pic2.png"><br><a href="/notherpage2.html" onMouseOver="show()" onMouseOut="hide()" ><img src="pic3.png"><br><a href="/lastpage.html" onMouseOver="show()" onMouseOut="hide()" ><img src="pic4.png"></div> <script type="text/javascript"> function show(){ document.getElementById("div1").style.display="block"; } function hide(){ document.getElementById("div1").style.display="none"; } </script> Hi, so I thought I could mash two bits of code together like this: Code: <div><label for="or">From:</label> <select name="or" style="width:200px; float: right" id="or" onchange="populate(this)"> <option value="Choose">Select your starting point</option> <option value="Guatemala">Guatemala City</option> <option value="Xela">Quetzaltenango</option> <option value="Antigua">Antigua</option> <option value="Rio Dulce">Rio Dulce</option> <option value="Coban">Coban</option> </select></div> <div> <label for="de">To:</label> <select name="de" style="width:200px; float: right" id="de"></select> </div> <div> <br> <input type="button" onclick="searchLocations()" value="Show route" /> </div> </div> </div> </div> <script type="text/javascript"> if (GBrowserIsCompatible()) { var gpolylines = []; function populate(o) { d=document.getElementById('de'); if(!d){return;} var mitems=new Array(); mitems['Choose']=['']; mitems['Guatemala']=['Select Destination','Antigua','El Rancho junction','San Pedro La Laguna','Panajachel','Coban','Rio Hondo','Chiquimula','Esquipulas','Copan Ruinas (Honduras)','La Ruidosa junction','Rio Dulce','Flores (via Rio Dulce)','Puerto Barrios','Flores (via Coban)','Quetzaltenango']; mitems['Xela']=['Select Destination','Guatemala City','Antigua','Chichicastenango','Huehuetenango','Panajachel','San Pedro La Laguna']; mitems['Antigua']=['Select Destination','Guatemala City','Quetzaltenango','Escuintla','Monterrico','San Pedro la Laguna','Panajachel','Chichicastenango']; mitems['Rio Dulce']=['Select Destination','Guatemala City','Flores','Lanquin','Coban','Puerto Barrios']; mitems['Coban']=['Select Destination','Lanquin','Rio Dulce','Laguna Lachua NP','Flores']; d.options.length=0; cur=mitems[o.options[o.selectedIndex].value]; if(!cur){return;} d.options.length=cur.length; for(var i=0;i<cur.length;i++) { d.options[i].text=cur[i]; d.options[i].value=cur[i]; } } function searchLocations() { var found = false; var from = document.getElementById('or').value; var to = document.getElementById('de').value; for (var a = 0; a < gpolylines.length; a++) { if (gpolylines[a].myname.toLowerCase() == to.toLowerCase() && gpolylines[a].mycategory.toLowerCase() == from.toLowerCase()) { found = true; gpolylines[a].show(); } } if ( ! found ) alert("No matches found. Please check your spelling or refine your search."); } the first bit, which populates the select boxes works fine, as you can see here but the second bit (the searchLocations function) is giving me a bit more trouble. What it's supposed to be doing is saying that if there's a polyline whose category xml attribute matches the text from the 1st select box AND whose name attribute matches the 2nd select box, it should be shown. The methods have worked in the past, there are no errors reported - the only problem is I get the alert regardless of which option I am selecting. I suspect that the problem is in the if (gpolylines[a].myname.toLowerCase() == to.toLowerCase() && gpolylines[a].mycategory.toLowerCase() == from.toLowerCase()) line, as it's the only one that I really came up with on my own... or can I not get the "or" and "de" elements in that way? Or is it something else entirely? thanks in advance for any suggestions...
