my function really slows down after 4 times

I wrote this, and after changing the value of the dropdown like 20 times, I noticed the function got slower and slower until I was not able to select a value after about 6 times. I tried optimizing it, it was 3 times, now 6.

Not quite sure where I dropped the ball at here, or what is consuming large amounts or resources.

So instead of going back to the server to get fresh values, I just took them from the html in the option list of the dropdownlist, and parsed out the values I wanted.

Anyways, any insight would be appreciated.

$('[id*="_ddl_EstimateShipping_RateAPICode"]').change(function () {
        
   var option_Textline = $(this).find(":selected").text();
   if (option_Textline != "") {

      // Parse the option_Textline
      var n = option_Textline.indexOf("--");
      var option_RateName = option_Textline.substring(0, n).trim();
      var option_RatePrice = option_Textline.substring(n + 2, option_Textline.length).trim();

      // Strip all the alpha-numeric chars from the value
      option_RatePrice = parseFloat(option_RatePrice.replace(/[A-Za-z$-]/g, ""));

            $('[id*="_lbl_Information_ShipRatePlan"]').text(option_RateName);
            $('[id*="_lbl_Information_ShipRatePrice"]').text("$" + option_RatePrice);

      // Update the Estimated Shopping Cart Totals
      var n_ProductTotals = $('[id*="_txt_Helper_ProductTotals_Field"]').val();
      var o_PromoDiscount = $('[id*="_lbl_PromoCode"]').text();
      var o_GCertificate = $('[id*="_lbl_SubTotals_GiftCertificates"]').text();
      var o_SalesTax = $('[id*="_lbl_SubTotals_SalesTax"]').text();

      o_PromoDiscount = parseFloat(o_PromoDiscount.replace(/\$/g, "").replace(/\-/g, ""));
      o_GCertificate = parseFloat(o_GCertificate.replace(/\$/g, "").replace(/\-/g, ""));
      o_SalesTax = parseFloat(o_SalesTax.replace(/\$/g, ""));

      var n_SubTotal = parseFloat(n_ProductTotals - parseFloat(o_PromoDiscount));
      var n_GrandTotal = parseFloat(parseFloat(n_SubTotal) + parseFloat(option_RatePrice) + parseFloat(o_SalesTax) - parseFloat(o_GCertificate));

      if (!isNaN(n_SubTotal)) {
          //n_SubTotal = Math.round(n_SubTotal * 100) / 100
          $('[id*="_lbl_DisplayShoppingCart_SubTotals_SubTotal"]').text("$" + n_SubTotal.toFixed(2));
      }

      if (!isNaN(option_RatePrice)) {
          //option_RatePrice = Math.round(option_RatePrice * 100) / 100
          $('[id*="_lbl_SubTotals_Shipping"]').text("$" + option_RatePrice.toFixed(2));
            }

      if (!isNaN(n_GrandTotal)) {
          //n_GrandTotal = Math.round(n_GrandTotal * 100) / 100
          $('[id*="_lbl_SubTotals_GrandTotal"]').text("$" + n_GrandTotal.toFixed(2));
      }
  }

    });

    return false;

Well after much diagnosing and more optimizing, the function I posted has nothing to due with the slowness.

Other dropdownlist are doing the same thing as well, even on other pages. Maybe I just need to reboot my computer an clean things up

trouble using each in json array

jkirkerx23-Aug-12 12:56

I'm having trouble using each on this json. Normally I use

for ( i=0; i<=states_array_Len-1; i++) {
   var stateName = states_array(i).states_Name
}

but in this case, each state name is different and I need the state code as well.

I'm thinking maybe I need a double $(each), I'm not sure.

On this sample, I get 0 in the dropdown list

my json

{
    "exit_Code": 2,
    "states_Count": 58,
    "states_Array": [
        {
            "Choose State": "--",
            "Alabama": "AL",
            "Alaska": "AK",
            "Arizona": "AZ",

my jquery

var objB = jQuery.parseJSON(responseText.d);
exitCode = objB.exit_Code;
var states_Count = objB.states_Count;
var states_Array = objB.states_Array;
var states_Array_Len = objB.states_Array.length;

if (exitCode == 0) {
   $('[id*="_ddl_Modal_StateCode_Field"]').empty();

   // US States
   $.each(states_Array, function (key, value) {
       $('[id*="_ddl_Modal_StateCode_Field"]').append($("<option ></option>").html(key).attr("value", value));
   });
}

JavaScript's for loop does what you want:

for(var stateName in states_Array){
 var stateShortCode = states_Array[statesName];
 // ...
}

It seems like you have that dictionary backwards, the short code should be the key and the long name the value.

Also, in your sample, exit_Code is non-zero so the inner code won't ever run. That's probably all that's needed to make it run, as I imagine jQuery.each uses a for loop already.

I didn't think of your example.

I thought of this last night while bowling, and it worked. I'm kind of surprised it works, but it makes sense. I just had to get into the array object before using $(each). Must be that double $(each) I was thinking of yesterday, in which the first $(each) is the array, and the 2nd $(each) is the pair value.

// Mexican States - "Baja Norte", "BN"
for (i = 0; i <= states_Array_Len - 1; i++) {
  $.each(states_Array[i], function (key, value) {
    $('[id*="_ddl_Modal_StateCode_Field"]').append($("<option ></option>").html(key).attr("value", value));
    });
}

my date is 29/02/2012 and i want to add 1 day to this date the answer should be 01/03/2012. how it is possible.I tried the following way, but not working.

var Dte="29/02/2012"

var today=new Date(Dte.substring(6,10),Dte.substring(3,5),Dte.substring(0,2));

today.setDate(today.getDate()+1);

As you are trying to create the date from a specific string, you should realise that the problem is actually at the point that you parse the date. Basically the to indexes in your substrings are out by one.

Try:

JavaScript

var today = new Date(Dte.substring(6,9), Dte.substring(3,4), Dte.substring(0,1));

I'm stumped.

I'm trying to load some thumbnails across in a row.

Each thumbnail has a div container that is white, 60x60, and a 3px margin.

This version loads the thumbnails across, but the 60x60 container is missing, and is not white. Just the image.

Maybe another set of eyes can see my mistake in the div element

var tr_tContainer_Row1 = table_tContainer.insertRow(-1);
var td_tContainer_Row1 = document.createElement("td");
td_tContainer_Row1.style.height = "119px";
td_tContainer_Row1.style.width = "auto";
td_tContainer_Row1.style.textAlign = "left";
td_tContainer_Row1.style.paddingLeft = "5px";
td_tContainer_Row1.style.overflow = "hidden";
td_tContainer_Row1.style.verticalAlign = "top";
td_tContainer_Row1.style.paddingTop = "5px";
tr_tContainer_Row1.appendChild(td_tContainer_Row1);

for (i = 0; i <= objT.length - 1; i++) {

    var image_Name = objT[i].image_Name;
    var image_Url = objT[i].image_Thumbnail;
    var image_Date = objT[i].image_PostDate;

    var div_ImagePreview = document.createElement("div");
    div_ImagePreview.style.position = "relative";
    div_ImagePreview.style.display = "inline";
    div_ImagePreview.style.cssFloat = "left";
    div_ImagePreview.style.clear = "left";
    div_ImagePreview.style.height = "60px";
    div_ImagePreview.style.width = "60px";
    div_ImagePreview.style.backgroundColor = "rgb(255,255,255)";
    div_ImagePreview.style.verticalAlign = "middle";
    div_ImagePreview.style.textAlign = "center";
    div_ImagePreview.style.margin = "6px";

    td_tContainer_Row1.appendChild(div_ImagePreview);

    var img_ImagePreview = document.createElement("img");
    img_ImagePreview.style.cssFloat = "left";
    img_ImagePreview.verticalAlign = "middle";
    img_ImagePreview.src = objT[i].image_Thumbnail;
    div_ImagePreview.appendChild(img_ImagePreview);
}

// Consider loading the first image
$('[id*="_panel_Gallery_Thumbnails"]').append(table_tContainer);

maybe it can't be done, so this will do for now

                    div_ImagePreview.style.clear = "none";
                    div_ImagePreview.style.textAlign = "center";
                    div_ImagePreview.style.margin = "2px";
                    div_ImagePreview.style.cursor = "pointer";
                    div_ImagePreview.style.cursor = "hand";
                    td_tContainer_Row1.appendChild(div_ImagePreview);

                    var img_ImagePreview = document.createElement("img");
                    img_ImagePreview.style.padding = "4px";
                    img_ImagePreview.style.border = "solid 1px rgb(220,220,220)";
                    img_ImagePreview.style.backgroundColor = "rgb(255,255,255)";
                    img_ImagePreview.src = objT[i].image_Thumbnail;
                    img_ImagePreview.alt = objT[i].image_Name;

Margins are outside the element, and not painted in the background colour. Try padding instead.

how to get default signature in outlook using Javascript

Hi All,
Have a code which sends an Outlook mail using Javascript by creating an instance of ActiveX object.
I need the functionality to be such, when the user executes this code his default signature should also be added in the mail...Have tried it but to no avail..Any help would be highly appreciated...
The code goes as follows for the reference:

function mailWindowOpen(mailBody) {
     outlookApp = new ActiveXObject("Outlook.Application");
     var nameSpace = outlookApp.getNameSpace("MAPI");
     mailFolder = nameSpace.getDefaultFolder(6);
     mailItem = mailFolder.Items.add('IPM.Note.FormA');
     mailItem.Subject = "Hi There!!!";
     mailItem.HTMLBody = mailBody;

     mailItem.display(0);

 }

mailBody is passed as a parameter from an aspx page, which has the Page.ClientScript.RegisterStartScript command to call this Javascript function...

There is a suggestion that calling GetInspector() on the mailItem will populate the signature. I've never tried it in JavaScript, but it may work for you.

I found more details in this[^] blog posting.

This isn't really a JS question. You need to look at Outlook's API documentation, I think.
