JavaScript is not printing my HTML - javascript

I have this function:
function suggestSell() {
var sellValue = document.getElementById('sellValue');
var btcVol = document.getElementById('btcVol');
var grossSell = btcVol * sellValue ;
var sellFee = grossSell * .006;
var sellOff = grossSell - sellFee;
document.write('<p>sellValue: ' + sellValue.innerHTML +
'<br> btcVol: ' + btcVol.innerHTML +
'<br> grossSell: ' + grossSell +
'<br> sellFee: ' + sellFee +
'<br> sellOff: ' + sellOff +
'<br></p>');
}
that i call like this:
<script>suggestSell();</script>
But it displays this in the browser.
1156.161.42053359undefinedundefinedundefined

var sellValue = document.getElementById('sellValue');
selects the node. You probably need the value
var sellValue = document.getElementById('sellValue').value;
Same thing for btcVol
var btcVol = document.getElementById('btcVol').value;
If you do make this change, note that sellValue.innerHTML and btcVol.innerHTML should be changed appropriately.

How do I hyperlink JSON API return values with variable URL addresses?

I have an HTML/CSS search bar where people can type a keyword and, on click, my Open States JSON API code returns New Jersey state bills that match that keyword.
Search Bar Screenshot
Screenshot of a Result
I want the bill titles that are returned to be hyperlinked to their page on the New Jersey state legislature site, but I can only find instructions for how to hyperlink a return with a static site.
Here is my JavaScript code so far (with API key removed):
e.preventDefault();
// console.log($("#billID").val());
var billSearchValue = $("#billID").val();
if(billSearchValue=='')
{
alert("Enter Desired Query Parameters");
} else{
// console.log(billSearchValue);
}
var searchQuery = "&q=" + billSearchValue;
var baseUrl = "http://openstates.org/api/v1/bills/?state=nj";
var apiKey = "";
var apiKeyParam = "&apikey=";
var apiKeyParams = apiKeyParam + apiKey;
var urlJSON = baseUrl + searchQuery + apiKeyParam + apiKey;
// console.log(urlJSON);
$.getJSON(urlJSON, function (data) {
var billsVar = [];
$.each(data, function(key, val) {
billsVar.push(val);
});
for (var i = 0; i < billsVar.length; i++) {
var billList = "<li>Bill <ul class=\"ul-sub\">"
var billTitle = "<li><strong>Bill Title</strong>: " + billsVar[i]['title'] + "</li>";
var billCreatedAt = "<li><strong>Bill Created</strong>: " + billsVar[i]['created_at'] + "</li>";
var billUpdatedAt = "<li><strong>Bill Updated</strong>: " + billsVar[i]['updated_at'] + "</li>";
var billID = "<li><strong>ID</strong>: " + billsVar[i]['id'] + "</li>";
var billChamber = "<li><strong>Bill Chamber</strong>: " + billsVar[i]['chamber'] + "</li>";
var billState = "<li><strong>Bill State (Probably Don't Want/Need This)</strong>: " + billsVar[i]['state'] + "</li>";
var billSession = "<li><strong>Bill Session</strong>: " + billsVar[i]['session'] + "</li>";
var billType = "<li><strong>Bill Type</strong>: " + billsVar[i]['type'] + "</li>";
var billSubjects = "<li><strong>Subjects</strong>: " + billsVar[i]['subjects'] + "</li>";
var billBillID = "<li><strong>Bill ID</strong>: " + billsVar[i]['bill_id'] + "</li>";
var billOutput = billList + billTitle + billCreatedAt + billUpdatedAt + billID + billChamber + billState + billSession + billType + billSubjects + billBillID + "</ul></li>";
$("#jsonlist").append(billOutput);
}
});
})
});
After a bit of research I see that a bill hyperlink is like this:
http://openstates.org/nj/bills/{Bill Session}/{Bill ID}/
I can't test my code because I have no API key, but the solution could be something like:
var billTitle = '<li><strong>Bill Title</strong>: '
+ '<a href="http://openstates.org/nj/bills/' +
billsVar[i]['session'] + '/' + billsVar[i]['bill_id'].split(' ').join('') + '/">'
+ billsVar[i]['title'] + '</a></li>';

How to get next row of HTML table based on some condition using jQuery?

Ok, I am new to JQuery and I have requirement to do some manipulation on table based on rows.
The table consists of rows which belong to 3 different style classes Brand have category and category have products.
var table = $("table tbody");
table.find(".brand").each(function(i) {
var $tdsBrand = $(this).find("td"),
brand = $tdsBrand.eq(0).text(),
atyBrand = $tdsBrand.eq(1).text(),
alyBrand = $tdsBrand.eq(2).text();
console.log('Brand Row ' + (i + 1) + ':\nBrand Name: ' + brand + '\nActual TY: ' + atyBrand + '\nActual LY: ' + alyBrand);
var brandClass = $(this).attr("class");
console.log('brand class : ' + brandClass);
if (this row has next row as category) {
//if(brand.next($( "tr[class='category']" ))) {
//if ("(.band):has(.category)") {
//if ($(this).parents(".category").length == 1) {
table.find(".category").each(function(i) {
var catClass = $(this).attr("class");
console.log('category class : ' + catClass);
var $tdsCategory = $(this).find("td"),
category = $tdsCategory.eq(0).text(),
atyCategory = $tdsCategory.eq(1).text(),
alyCategory = $tdsCategory.eq(2).text();
console.log('Category Row ' + (i + 1) + ':\nCategory Name: ' + category + '\nActual TY: ' + atyCategory + '\nActual LY: ' + alyCategory);
if (This row has next row as product) {
//if(next($( "tr[class='product']" ))) {
//if ("(.category):has(.product)") {
//if ($(this).parents("product").length == 1) {
table.find(".product").each(function(i) {
var proClass = $(this).attr("class");
console.log('product class : ' + proClass);
var $tds = $(this).find("td"),
product = $tds.eq(0).text(),
aty = $tds.eq(1).text(),
aly = $tds.eq(2).text();
console.log('Product Row ' + (i + 1) + ':\nProduct Name: ' + product + '\nActual TY: ' + aty + '\nActual LY: ' + aly);
});
}
});
}
});
What I want to do is, I have to sum up Actual TY values of products and display them on their category. Then sum up Actual TY of categories (which has been calculated from products for different categories) to their brand.
Please refer http://jsfiddle.net/cfhhz0zr/46/ for clear understanding of my requirement and code which I've tried till now.
Thank you.
Just modified a bit your code and it seems that is doing what you are looking for. See also the http://jsfiddle.net/88prg1dt/
I refactored a bit and renamed some variables to make a bit more sense so should be fairly clear now. If you want to calculate the total for a product / category now should be really super simple.
Here is the JS code:
var $table = $("table tbody");
$table.find(".brand").each(function (brandIndex) {
var $brandRow = $(this);
var $tdsBrand = $(this).find("td");
var brandName = $tdsBrand.eq(0).text();
var atyBrand = $tdsBrand.eq(1).text();
var alyBrand = $tdsBrand.eq(2).text();
console.log('Brand Row ' + (brandIndex + 1) + ':\nBrand Name: ' + brandName + '\nActual TY: ' + atyBrand + '\nActual LY: ' + alyBrand);
var $categoryRows = $brandRow.nextUntil('.brand').filter('.category');
$categoryRows.each(function (categoryIndex) {
var $categoryRow = $(this);
var $tdsCategory = $categoryRow.find("td");
var categoryName = $tdsCategory.eq(0).text();
var atyCategory = $tdsCategory.eq(1).text();
var alyCategory = $tdsCategory.eq(2).text();
console.log('Category Row: ' + (categoryIndex + 1) + ':\nCategory Name: ' + categoryName + '\nActual TY: ' + atyCategory + '\nActual LY: ' + alyCategory);
var $productRows = $categoryRow.nextUntil('.brand, .category').filter('.product');
$productRows.each(function (productIndex) {
var $productRow = $(this);
var $tdProducts = $productRow.find("td");
var productName = $tdProducts.eq(0).text();
var atyProduct = $tdProducts.eq(1).text();
var aly = $tdProducts.eq(2).text();
console.log('Product Row ' + (productIndex + 1) + ':\nProduct Name: ' + productName + '\nActual TY: ' + atyProduct + '\nActual LY: ' + aly);
});
});
});
I played a bit with jQuery nextUntil() method as the documentation:
Description: Get all following siblings of each element up to but not
including the element matched by the selector, DOM node, or jQuery
object passed.
Is this answering your question ?

Generate arrays using dynamically generated forms

Basically, I'm using JavaScript to dynamically generate a form that allows from multiple entries within a single submission. Here's the code I'm using for that:
function addEvent()
{
var ni = document.getElementById('myDiv');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value - 1) + 2;
numi.value = num;
var divIdName = 'my' + num + 'Div';
var newdiv = document.createElement('div');
newdiv.setAttribute('id', divIdName);
newdiv.innerHTML = '<table id="style" style="background-color: #ffffff;"><tr><td colspan="2">Entry ' + num + '<hr \/><\/td><\/tr><tr><td><label>Item 1: <\/td><td><input name="item1_' + num + '" value="" type="text" id="item1" \/><\/label><\/td><\/tr><tr><td><label>Item 2: <\/td><td><input name="item2_' + num + '" type="text" id="item2" \/><\/label><\/td><\/tr><tr><td><label>Item 3: <\/td><td><input type="text" name="item3_' + num + '" id="item3" \/><\/label><\/td><\/tr><tr><td><label>Item 4: <\/td><td><select name="item4_' + num + '" id="item4"><option value="---">---<\/option><option value="opt_1">1<\/option><option value="opt_2">2<\/option><option value="opt_3">3<\/option><option value="opt_4">4<\/option><\/select><\/label><\/td><\/tr><\/table>';
ni.appendChild(newdiv);
}
This works just fine, generating the entries fields I need. Using console in-browser, I've even verified all the names are correct. The issue is that I need to then take the selections and generate output. I've tried several methods, but everything resulted in null values.
function generateVideo()
{
var entries = document.getElementById('theValue').value;
var item1 = {};
var item2 = {};
var item3 = {};
var item4 = {};
for(i = 1; i <= entries; i++)
{
item1[i - 1] = document.getElementById('item1_' + i);
item2[i - 1] = document.getElementById('item2_' + i);
item3[i - 1] = document.getElementById('item3_' + i);
item4[i - 1] = document.getElementById('item4_' + i);
}
var code = 'Copy code and paste it into Notepad<br \/>"Save as" filename.html<br \/><textarea name="" cols="45" rows="34">header template\n';
for(i = 0; i < entries; i++)
{
if(i != (entries - 1))
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"],\n';
}
else
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"]\n';
}
}
code = code + 'footer template<\/textarea>';
var result = document.getElementById("result");
result.innerHTML = code;
}
The output is as follows:
Copy code and paste it into Notepad<br />"Save as" CourseName_Unit_Chapter.html<br /><textarea name="" cols="45" rows="34">header template
["null", "null", "null", "null"]
footer template</textarea>
Now, certain fields can be null, that's fine (I'll do form validation after I get it working), but I'm getting null for every field regardless of what is entered.
I, originally, had the .value on the getElementByIds, but that only results in the script not running when the entries variable is greater than 0 (default), which is why I tried removing them.
function generateVideo()
{
var entries = document.getElementById('theValue').value;
var item1 = {};
var item2 = {};
var item3 = {};
var item4 = {};
for(i = 1; i <= entries; i++)
{
item1[i - 1] = document.getElementById('item1_' + i).value;
item2[i - 1] = document.getElementById('item2_' + i).value;
item3[i - 1] = document.getElementById('item3_' + i).value;
item4[i - 1] = document.getElementById('item4_' + i).value;
}
var code = 'Copy code and paste it into Notepad<br \/>"Save as" filename.html<br \/><textarea name="" cols="45" rows="34">header template\n';
for(i = 0; i < entries; i++)
{
if(i != (entries - 1))
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"],\n';
}
else
{
code = code + ' ["' + item1[i] + '", "' + item2[i] + '", "' + item3[i] + '", "' + item4[i] + '"]\n';
}
}
code = code + 'footer template<\/textarea>';
var result = document.getElementById("result");
result.innerHTML = code;
}
I've also tried variations of multidimensional arrays, instead of four arrays, but got the same results.
The output, as indicated by the removal of the .value on the getElementByIds, is good. Basically, there is something wrong with my attempts to populate the arrays using the dynamically generated forms.
I suspect that the issue with the declaration of the element ID, but I'm not sure how else to declare it. This style of scripting is not my norm. ^^'
Anyone have any ideas on how to fix the for loop to generate the array?
replace all occurences of
itemN[i]
with
itemN[i].value
if that doesnt work add
console.log( itemN[i] )
and see what it outputs

What is the optimal way to load form data into a string and then to localStorage?

Is this the optimal way to load form data into a string and then to localStorage ?
I came up with this on my own, and I am not good in programming. It works, for what I need, but I am not sure if it's a bulletproof code?
<script>
var sg = document.getElementById("selectedGateway");
var sd = document.getElementById("selectedDestination");
var dm = document.getElementById("departureMonth");
var dd = document.getElementById("departureDay");
var dy = document.getElementById("departureYear");
var rm = document.getElementById("returnMonth");
var rd = document.getElementById("returnDay");
var ry = document.getElementById("returnYear");
var ad = document.getElementById("adults");
var ch = document.getElementById("option2");
$("#searchRequestForm").submit(function() {
var string = 'From: ' + sg.value + ' \nTo: ' + sd.value + ' \nDeparture: ' + dm.value + '/' + dd.value + '/' + dy.value + ' \nReturn: ' + rm.value + '/' + rd.value + '/' + ry.value + ' \nNumber of adults: ' + ad.value + ' \nNumber of children: ' + ch.value;
localStorage.setItem("string", string);
});
</script>
I would use something like the following so that I could deal with an object and its properties rather than a big string. Note that other than the jQuery selectors, this is pure JavaScript.
Demo: http://jsfiddle.net/grTWc/1/
var data = {
sg: $("#selectedGateway").val(),
sd: $("#selectedDestination").val()
// items here
};
localStorage.setItem("mykey", JSON.stringify(data));
To retrieve the data:
var data = JSON.parse(localStorage["mykey"]);
alert(data.sg);
See Also:
https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify
http://api.jquery.com/jQuery.parseJSON/
I prefer a table driven approach so there is no repeated code (DRY):
var ids = [
"selectedGateway", "From: ",
"selectedDestination", "\nTo :",
"departureMonth", "\nDeparture: ",
"departureDay", "/",
"departureYear", "/",
"returnMonth", " \nReturn: ",
"returnDay", "/",
"returnYear", "/",
"adults", " \nNumber of adults: ",
"option2", " \nNumber of children: "];
var submitStr = "";
for (var i = 0; i < ids.length; i+=2) {
submitStr += ids[i+1] + document.getElementById(ids[i]).value;
}
localStorage.setItem("string", submitStr);
You could define a function such as the one below to directly get the values by id so then it would be simpler when you build your string.
function form(id) {
return document.getElementById(id).value;
}

Cant refresh to bottom of page with javascript function containing url variables

I have a few cascading dropdowns on the bottom of my php page. Each time a user selects an option from the dropdown the following function is called to add the value of that option to my url variables. Currently the page refreshes to the top each time which is a huge problem. Normally I would use something like onCLick="window.location='page.htm#bottom';" to refresh to the bottom of the page but the below function stops working when I add the #bottom. Can someone help me adjust this function or give me other ideas that will refresh to the bottom of the page when the function is done.
function reload5(form){
if(document.getElementById('fda1').checked) {
var fda = '1';
}else if(document.getElementById('fda0').checked) {
var fda = '0';
}
var val=form.category.options[form.category.options.selectedIndex].value;
var val2=form.subcat.options[form.subcat.options.selectedIndex].value;
var val3=form.subcat1.options[form.subcat1.options.selectedIndex].value;
var val4=form.subcat2.options[form.subcat2.options.selectedIndex].value;
var comp1=form.mname.options[form.mname.options.selectedIndex].text;
var itemnum=document.getElementById('item').value;
var desc=document.getElementById('desc').value;
var quan=document.getElementById('quan').value;
var list=document.getElementById('list').value;
var uom=form.uom.options[form.uom.options.selectedIndex].text;
self.location='add_products.php#bottom?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 ;
}
So this doesn't work: self.location='add_products.php#bottom?fda=' + fda
But this does : self.location='add_products.php?fda=' + fda
Any idea where to put the #bottom?
The issue is that the hash must come after the query string at the end. See this article. Try this... (I also cleaned up the code)
function reload5(form){
var val=form.category.options[form.category.options.selectedIndex].value,
val2=form.subcat.options[form.subcat.options.selectedIndex].value,
val3=form.subcat1.options[form.subcat1.options.selectedIndex].value,
val4=form.subcat2.options[form.subcat2.options.selectedIndex].value,
comp1=form.mname.options[form.mname.options.selectedIndex].text,
itemnum=document.getElementById('item').value,
desc=document.getElementById('desc').value,
quan=document.getElementById('quan').value,
list=document.getElementById('list').value,
uom=form.uom.options[form.uom.options.selectedIndex].text,
fda;
if(document.getElementById('fda1').checked) {
fda = 1;
} else if(document.getElementById('fda0').checked) {
fda = 0;
} else {
fda = -1;
}
window.self.location.href = 'add_products.php?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 + "#bottom";
}
What I don't understand is why you are not doing something with Ajax that would not cause the page to refresh at all.
