Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    simple Javascript question

    I have a function that builds a data object that I pass to a client side template.

    When I pass the data output as text everything works fine, but when I try to pass the results of the javascript it does not work.

    I have made a short video to show the problem. After the first minute the video goes black but it has explained everything by that time.


    https://www.youtube.com/watch?v=W_q7GvF3wNA

    function cart() {


    var count = {dialog.Object}._getRepeatingSectionRowCount('CONTAINER_2',true);

    var name = "Lunch";
    var location = "Central";
    var total = 0;
    var text = "[";
    var res = '';
    var i;


    for (i = 1; i <= count; i++) {
    var Qty = {dialog.object}.getValue('Qty' + ':' + i);
    var Desc = {dialog.object}.getValue('Desc' + ':' + i);
    var Price = {dialog.object}.getValue('Price' + ':' + i);


    text += "{qty: " + Qty + " , " + "desc: '" + Desc + "' , " + "price: " + Price + " , res: '' " + "}," + "<br>";

    total = total + parseInt(Price)


    }
    i = count
    var Qty = {dialog.object}.getValue('Qty' + ':' + i);
    var Desc = {dialog.object}.getValue('Desc' + ':' + i);
    var Price = {dialog.object}.getValue('Price' + ':' + i);

    text += "{qty: '' " + " , " + "desc: '" + "<strong> Total</strong>" + "' , " + "price: " + total + " , res: 'style= " + "\" text-align:right\"'" + "}]" ;
    var before = "[{meal: '" + name + "', location: '" + location + "', table: "

    text = before.concat(text);
    text += "}];";


    // the following three lines of code are for testing to look at the result.

    document.getElementById("demo").innerHTML = text;
    var text = document.getElementById("demo").innerHTML ;

    document.getElementById("copy").innerHTML = text;

    // I have cut and pasted from the div and manually set the obj to the output of text if I don't do this I cannot get it to work.

    obj = [{meal: 'Lunch', location: 'Central', table: [{qty: 1 , desc: 'BLT' , price: 50 , res: '' },
    {qty: 2 , desc: 'Classic Club' , price: 100 , res: '' },
    {qty: 4 , desc: 'Santa Fe' , price: 200 , res: '' },
    {qty: 3 , desc: 'Breakfast Special' , price: 150 , res: '' },
    {qty: '' , desc: ' Total' , price: 500 , res: 'style= " text-align:right"'}]}];


    return obj
    }

    Re: simple Javascript question

    Here's why pasting works and "text" doesn't.

    This:

    text is a String. You are building a String.

    This, however:
    Originally posted by Michael1954 View Post
    obj = [{meal: 'Lunch', location: 'Central', table: [{qty: 1 , desc: 'BLT' , price: 50 , res: '' },
    {qty: 2 , desc: 'Classic Club' , price: 100 , res: '' },
    {qty: 4 , desc: 'Santa Fe' , price: 200 , res: '' },
    {qty: 3 , desc: 'Breakfast Special' , price: 150 , res: '' },
    {qty: '' , desc: ' Total' , price: 500 , res: 'style= " text-align:right"'}]}];
    is an Array of Objects. I'm going to take a wild guess here that your calling function wants and Array of Objects and not a String. ;)

    You need to change your code to build an Object, not a string. When you write obj = text, you are assigning a String into a String.

    Try something like this:
    Code:
    var obj = new Array();
obj[0] = new Object();
obj[0].meal = 'Lunch';
obj[0].location = 'Central';

var table = new Array();
var total = 0;
for (i = 1; i <= count; i++) {
    var Qty = {dialog.object}.getValue('Qty' + ':' + i);
    var Desc = {dialog.object}.getValue('Desc' + ':' + i);
    var Price = parseInt({dialog.object}.getValue('Price' + ':' + i));
    table.push({qty: Qty, desc: Desc, price: Price, res: ''});

    total = total + Price;
}

table.push({qty: '', desc: ' Total', price: total, res: 'style="text-align:right;"'});

obj[0].table = table;

return obj;
    Good luck!

        Thanks Sarah worked a dream. Client side templating is so useful that building these objects is a must.

        If you go to Hong Kong I will see you are well supplied with Bagels.
