How do I Separate an Array Value from input to HTML - javascript

I'm getting this value from the page source (after the page finished loading), the data is coming from a back-end process that populates a hidden text input on the page. I wish to separate this data and then display it in HTML format.
This is the code from 'View Page Source'
<input name="hiddenUserStats" type="hidden" id="hiddenUserStats" value="
99.0~35.0~8.0~.0~1.0~6.0~3.0~.0~1.0~3.8~1.8~1.0~.0~16.0" />
On the value, I'm assuming that each .0~ separates the true value that I wish to separate and display. Anyone know what would be the best step to separate and display such data? Do I start with separating them in variables?

You can use split() function to separate your stats values.
var value = document.getElementById('hiddenUserStats').getAttribute('value');
var stats = value.split('~');
for (i = 0; i < stats.length; i++)
{
var div = document.createElement('div');
div.innerText = stats[i];
document.body.appendChild(div);
}
<body>
<input name="hiddenUserStats" type="hidden" id="hiddenUserStats" value="
99.0~35.0~8.0~.0~1.0~6.0~3.0~.0~1.0~3.8~1.8~1.0~.0~16.0" />
</body>

Here is another way using native array methods;
document.getElementById('hiddenUserStats')
.getAttribute('value')
.split('~')
.map(function(val, i) {
return '<div>' + i + ': '+ val + '</div>';
})
.forEach(function(el) {
document.body.innerHTML += el;
});

Form response blank

I have some google script that generates an initial form then gathers a number does a lookup and then is supposed to return a second form (getfamily function). The second form which is dynamically generated returns blank. I can see the formHTML variable with data in the logger, but it comes up blank in the browser. Any suggestions would be appreciated.
var ssID="xxx";
var rows = SpreadsheetApp.openById(ssID).getSheetByName("studentinfo").getDataRange().getValues();
function doGet() {
var html = HtmlService.createTemplateFromFile('index2').evaluate()
.setTitle('Lookup').setSandboxMode(HtmlService.SandboxMode.NATIVE);
return html;
};
function getfamily(form){
Logger.log(form.familyid);
var ssID="xxxx";
var rows = SpreadsheetApp.openById(ssID).getSheetByName("studentinfo").getDataRange().getValues();
var formHTML = "<!DOCTYPE html>";
formHTML +="Hello!";
formHTML += '<form id="students">';
var filteredRows = rows.filter(function(row){
var message="made it";
if (row[0] === form.familyid) {
Logger.log(row[2]);
formHTML+= '<input type="checkbox" name ="students value='+ row[1] + '">'+ row[2] + '<br>';
return row[2];
}
});
formHTML+='<input type="submit" value="CheckIn">';
formHTML+='</form>';
Logger.log(formHTML);
var output = HtmlService.createHtmlOutput(formHTML).setSandboxMode(HtmlService.SandboxMode.NATIVE);
return output;
};
Your input type="checkbox" line is hard to figure out what you want. I presume that you plan in insert this form into an already exist DOM so no need the worrying about other tags just stick it in whatever div you have prepared for it.
function getfamily(form){
var ssID="xxxx";
var rows = SpreadsheetApp.openById(ssID).getSheetByName("studentinfo").getDataRange().getValues();
var formHTML='<form id="students">';
var message="made it";
rows.forEach(function(row){
if (row[0]==form.familyid) {
formHTTML=Utilities.formatString('<input type="checkbox" name="students" value="%s" /><br />',row[2]);//I presume that you want to change the name but I cant tell how you planned to do it.
}
});
formHTML+='<input type="button" value="CheckIn" onClick="proceesForm(this.parentNode);" />';
formHTML+='</form>';
return HtmlService.createHtmlOutput(formHTML);
};
You can use submit if you really must but I find using google.script.run to be a lot easier. We need to see more of what you're doing to provide a complete answer.

javascript capture every value in a div

I have a div in which I render through javascript inputs and text dynamically. I am trying to capture the text of this div (both input values and text).
My first step if to capture the parent div:
let answerWrapper = document.getElementById("typing-answer-wrapper");
The issue now is that using the innerHTML will give me the whole html string with the given tags and using the inerText will give me the text, excluding the tags.
In the following case scenario:
the console inspect is:
What is the way to capture: $2.4 if the inputs have 2 and 4
and $null.null if the inputs are blank.
Any help is welcome
You could iterate over all of the element's child nodes and concatenate their wholeText or value else 'null'. For inputs the wholeText will be undefined. If they have no value we'll return 'null'. Be aware that spaces and line-breaks will also be included so you may want to strip these later (or skip them in the loop) but as a proof of concept see the following example:
var typingAnswerWrapper = document.getElementById("typing-answer-wrapper");
function getVal(){
var nodeList = typingAnswerWrapper.childNodes;
var str = "";
for (var i = 0; i < nodeList.length; i++) {
var item = nodeList[i];
str+=(item.wholeText || item.value || "null");
}
console.log(str);
}
getVal();
//added a delegated change event for demo purposes:
typingAnswerWrapper.addEventListener('change', function(e){
if(e.target.matches("input")){
getVal();
}
});
<div id="typing-answer-wrapper">$<input type="number" value=""/>.<input type="number" value="" />
</div>
Here's how you could do it :
function getValue() {
var parent = document.getElementsByClassName('typing-answer-wrapper')[0],
text = [];
const children = [...parent.getElementsByTagName('input')];
children.forEach((child) => {
if (child.value == '')
text.push("null")
else
text.push(child.value)
});
if (text[0] != "null" && text[1] == "null") text[1] = "00";
document.getElementById('value').innerHTML = "$" + text[0] + "." + text[1]
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.js"></script>
<div class="typing-answer-wrapper">
$
<input type="number"> .
<input type="number">
</div>
<button onclick="getValue()">get value</button>
<div id="value"></div>
You can fetch input feild values by their respective ids $('#input_feild_1').val() will give the first feild value and similarly $('#input_feild_2').val() for second feild and contruct use them to construct whatever as u wish. As in your case this should work
value_1 = $('#input_feild_1_id').val()
value_2 = $('#input_feild_2_id').val()
you need something like "$ + value_1 + . + value_2"

I am using a HTML page where I have multiple textbox inputs, lets say five for example. I have a submit button. Once I enter all values in the text boxes and hit submit, i want all the values to be displayed in the area below submit button on the document in an ascending order. I want to sort all the values to display as result. I just used an array to test if my concept is right, but no luck. Anyone could help is highly appreciated.
This is the code:
function myFunction() {
var txt = new array[];
var txt[0] = $('input:text[name=text1]').val();
var txt[1] = $('input:text[name=text2]').val();
var txt[2] = $('input:text[name=text3]').val();
var txt[3] = $('input:text[name=text4]').val();
var txt[4] = $('input:text[name=text5]').val();
txt.sort();
for (var i = 0; i < txt.length; i++) {
document.getElementById('txt[i]').value + ' ';
}
}
The .text-1, .text-2, etc are the classes of your input fields. The .val() will get the user input of those once they click on your submit button. The last line creates a new div and appends the user input to the results div.
$('.submit-button').on('click', function() {
aaa = $('.text-1').val();
bbb = $('.text-2').val();
ccc = $('.text-3').val();
ddd = $('.text-4').val();
eee = $('.text-5').val();
$('<div>' + aaa + '<br />' + bbb + '<br />' + ccc + '<br />' + ccc + '<br />' + ddd + '<br />' + eee + '</div>').appendTo('.results-div');
});
Here is a fiddle that does what I think you want done:
http://jsfiddle.net/KjHB3/3/
Here is the HTML code:
<input type="text" name="text1" id="text1" /><br/>
<input type="text" name="text2" id="text2" /><br/>
<input type="text" name="text3" id="text3" /><br/>
<input type="text" name="text4" id="text4" /><br/>
<input type="text" name="text5" id="text5" /><br/>
<input type="button" value="submit" id="submit" />
<div id="result">replace</div>
Here is the javascript code:
$("#submit").click(function() {
// Extract all the values into an array
var valArray = [];
$("input[type=text]").each(function(index, el) {
valArray[index] = jQuery(el).val();
});
// Output list of values (in order they appear in form)
$("#result").html("In order of text box: <ol id='list1'></ol>");
$.each(valArray, function(index, value) {
$("#list1").append("<li>" + value + "</li>");
});
// Output list of values (in sorted order)
$("#result").append("In sorted order: <ol id='list2'></ol>");
valArray = valArray.sort();
$.each(valArray, function(index, value) {
if (value != null && value != "") {
$("#list2").append("<li>" + value + "</li>");
}
});
});
Your code appears to be correct, except for the line document.getElementById('txt[i]').value + ' ';. There's nothing writing the values back to the document.
First, starting with the selector, you need to change 'txt[i]' to 'text'+i, because the browser is looking for an element with id txt[i] and finding nothing, thus doing nothing. Also, you should use jQuery, since it makes everything more concise.
Then, to write back to the document, you need to set the value. What your current code (.value + ' ';) does is it gets a value, then adds it to the string ' ', then the statement ends. What you need to do is to set the value of the string, with jQuery (.val(txt[i]);) or stock Javascript (.value = txt[i];).
So, to conclude, just swap the code inside the for loop in your code with this line:
$("input:text[name=text"+i+"]").val(txt[i]);
Let me break down your code in two part to show why it is not working yet.
function GetInputValues() {
var txt = new array[];
var txt[0] = $('input:text[name=text1]').val();
var txt[1] = $('input:text[name=text2]').val();
var txt[2] = $('input:text[name=text3]').val();
var txt[3] = $('input:text[name=text4]').val();
var txt[4] = $('input:text[name=text5]').val();
txt.sort();
return txt; // added by me to encapsulate getting the values
}
The first part of your function myFunction() is correct. You are using jQuery to get the values of the input boxes and writing the values into an array.
The second part has some mistakes:
for (var i = 0; i < txt.length; i++) {
document.getElementById('txt[i]').value + ' ';
}
The function document.getElementById("lastname") returns the html-element whose id is lastname. So in your for-loop you are trying to get the value but you already have the values in your array txt. On top this 'txt[i]' is only a string. So javascript tries to find an element that matches <... id="txt[i]" ...>. But you do not want to get the values you want to write the values back into the document. Assuming you have a div like this <div id='txt[i]'> ...</div> you could wrhite your code like this:
for (var i = 0; i < txt.length; i++) {
document.getElementById('txt[i]').innerHTML += txt[i];
}
Another way would be to join the array:
var myInputValues = GetInputValues(); // this returns your array txt
document.getElementById('myResult').InnerHTML = myInputValues.join(", ");
This assumes that you have a element with id=myResult for example <div id='myResult'>..</div>
Update to adress issues in your code
Your fiddle has this part:
myFunction(txt) { // <-- function declaration: there is something missing here
var myInputValues = GetInputValues(); // this returns your array txt
document.getElementById('myResult').InnerHTML = myInputValues.join(", ");
} //<--- this is the end of myfunction
}); // <-- these do not belong here
// you never execute myFunction
You have to define the function and later call it. Since your mistakes are so basic i really recommend to start with a tutorial to learn javascript. I can recommend Eloquent JavaScript:
to learn the basics of functions
to understand the basics about the Document-Object Model

Dynamically Load Div Elements and Assign IDs

I understand how to dynamically load HTML, I am having trouble understanding how I load it, assign, and keep track of IDs for elements inside the loaded div.
This is my main block
<div id="add-equip-container">
<div id="add-equip-content">
</div>
<button id="add-equipment">Add More Equipment</button>
<button id="submit-equipment">Submit Equipment</button>
</div>
Now, every time add-equipment is clicked, I want to load the following block into add-equip-content.
<div class="add-equip-form">
<input id="?" type="text" placeholder="Equipment Description..."/></br>
<input id="?" type="text" placeholder="Equipment Number"/></br>
<input id="?" type="text" placeholder="Other Stuff..."/></br>
</div>
Each block would be inserted beneath the previous one loaded. I have no idea how to assign and keep track of the various IDs that will be dished out during this operation. I would love a solution that does not involve jQuery. I am trying to lean vanilla JavaScript before I get into frameworks.
I am sure there may be a question or blog or something on this already, but I just don't know the best keywords to search for. Any time I use "Dynamically Load HTML" in the search keywords, all I get is AJAX Tutorial results.
Thanks in advance for any help!
One solution would be not actually load the HTML, but to create it via Javascript. This would be useful in your case as you are adding the same code to the page, only with different ID's. I would write a function like this:
var form_index = 0;
//elem is the element you are appending to.
function addForm(elem) {
//create the container
var form_container = document.createElement("div");
form_container.className = "add-equip-form";
//description input
var desc = document.createElement('input');
desc.id = "equip-desc-" + form_index;
desc.type = "text";
desc.placeholder = "Equipment Description...";
//Equipment number input
var num = document.createElement('input');
num.id = "equip-num-" + form_index;
num.type = "text";
num.placeholder = "Equipment Number";
//Other
var other = document.createElement('input');
other.id = "equip-other-" + form_index;
other.type = "text";
desc.placeholder = "Other Stuff...";
//append inputs
form_container.appendChild(desc);
form_container.appendChild(num);
form_container.appendChild(other);
//append form
elem.appendChild(form_container);
form_index++;
}
Then, to access your created ID's, all you need to know is the index of the containing div within your parent elem. See here for a javascript solution. Once you have the index, getting the form data is as easy as using your index to query based on ID's.
This should do it. You may or may not need to do the elements.push(content) if you don't need to refer back to these elements in an array. Could just iterate a counter instead.
var add_equip_content = document.getElementById('add-equip-content'),
add_equip_btn = document.getElementById('add-equipment'),
elements = [];
add_equip_btn.addEventListener('click', addEquipment, true);
function addEquipment(event){
var content = document.createElement('div'),
html = '';
content.className = 'add-equip-form';
html += '<input id="equip_' + elements.length + '" type="text" placeholder="Equipment Description..."/></br>';
html += '<input id="equip_' + elements.length + '" type="text" placeholder="Equipment Number"/></br>';
html += '<input id="equip_' + elements.length + '" type="text" placeholder="Other Stuff..."/></br>';
content.innerHTML = html;
add_equip_content.appendChild(content);
elements.push(content);
}

How to call on text from a textbox to set a variable in javascript

I have a bit of a predicament. I am trying to run a variable on a loop so that it can change the loop. Here is the code that I have at the present time.
<FORM NAME="myform" ACTION="" METHOD="GET">
<INPUT TYPE="text" NAME="inputbox" id="Variable"><P>
</FORM>
<script type="text/javascript">
document.getElementById("Variable").value = i;
var i=5;
for (i=0;i<=5;i++)
{
document.write(" " + i);
document.write("<br />");
}
</script>
I am trying to call upon the text in the textbox from the form in order to define var i. I would also like to point out that I am no master of HTML, and if you see that I have done this all wrong, feel free to tell me that it cannot be done.
I think you mean something like this:
var count = parseInt(document.getElementById("Variable").value, 10);
var i;
for (i = 0; i < count; ++i) {
// ...do something...
}
What that does:
Looks up the element by its ID (you already had that): document.getElementById("Variable').
Retrieves the value of its value property, which is a string.
Converts the string into an number via parseInt, using decimal (as opposed to octal or hexadecimal).
Loops from zero (inclusive) to that number (exclusive).
Note that you can't use document.write after the main parse (initial load) of the page, and you probably don't want to use the value from a form field before the main parse of the page is complete, so you probably won't be doing document.write here. You might set the innerHTML of an element, something like that.
Re my "...you can't use document.write after the main parse...": Technically, you can, but you'll completely replace the page rather than just adding to it.
Re my "...and you probably don't want to use the value from a form field before the main parse...is complete...": You can, though, as long as the form field is above the script in the page markup. I did literally mean you probably don't want to, presumably you want the user to enter some value first.
Update: Here's a more complete example, with a live copy to play with:
var element, value, count, i;
element = document.getElementById("Variable");
if (!element) {
display("Element 'Variable' not found.");
}
else {
value = element.value;
count = parseInt(value, 10);
if (isNaN(count)) {
display("'" + value + "' is not numeric");
}
else {
for (i = 0; i < count; ++i) {
display("Loop " + i);
}
}
}
function display(msg) {
var p = document.createElement('p');
p.innerHTML = msg;
document.body.appendChild(p);
}
Live copy, the display function is obviously a bit of a placeholder for whatever it is you actually want to do.
I did not understand your exact question. but I guess this is your solution :
<FORM NAME="myform" ACTION="" METHOD="GET">
<INPUT TYPE="text" NAME="inputbox" id="Variable">
<input type="button" value="run" onclick="renderIt()" />
<P>
</FORM>
<script type="text/javascript">
function renderIt()
{
var max = parseInt(document.getElementById("Variable").value);
for (i=0;i<=max;i++)
{
document.write(" " + i);
document.write("<br />");
}
}
</script>
