JavaScript Add Textbox Dynamically when Button onClick - javascript

I am trying to add a new textbox when add button is onclick using JavaScript. Here is my HTML:
htmlStr += "<div id='filterContent' style='width:100%;text-align:center;'>";
htmlStr += "<input id='startLoc' type='text' />";
htmlStr += "<input id='endLoc' type='text' />";
htmlStr += "<input id='addLoc' type='button' value='Add' onClick='addTextBox()' />";
htmlStr += "</div><br/>";
And here is my JavaScript to add a new textbox when button is onClick:
function addTextBox(){
var element = document.createElement("input");
element.setAttribute("type", "text");
element.setAttribute("value", "");
element.setAttribute("name", "Test Name");
//element.setAttribute("style", "width:200px");
var foo = document.getElementById("filterContent");
foo.appendChild(element);
}
It works perfectly to add as many textbox as I want. But somehow the textbox created share the same id. I wonder is that possible to add many textbox with different ID each time when the button is onClick?
Thanks in advance.

var aa=Math.random();
<input id='addLoc"+aa+"' type='text' />
User math.random to generate random id's for a textbox

Using your current setup you could keep track of an id increment in a global:
//outside function
var idIndex = 1;
function addTextBox(){
var element = document.createElement("input");
element.setAttribute("type", "text");
element.setAttribute("value", "");
element.setAttribute("name", "Test Name");
element.setAttribute("id", "addLoc" + idIndex++);
element.setAttribute("style", "width:200px");
element.onclick = function()
{
//do something
}
var foo = document.getElementById("filterContent");
foo.appendChild(element);
}
EDIT: To answer the question in this answer's comments. It is certainly possible to add a different onclick handler for every new textbox (although you're probably better off designing your handlers so you can use a single handler for all but if you wanted for some reason to use a different one you could bind an anonymous function to the handler, I have added an approach above).
EDIT2: Regarding the second question in the path there are two approaches you could use. Instead of calling the separate functions getFirstPath() getSecondPath() etc. individually, you could have a single function called getPath() and pass the index to it as a parameter:
var getPath = function(index) {
switch(index)
{
case 1:
return getFirstPath();
break;
case 2:
return getSecondPath();
break; //and so on.
}
}
And then your onclick would look like this:
element.onclick = function()
{
getPath(index);
}

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.

Create radio button dynamically in magento

I am new in magento,i have to develop extension in magento, in that extension i need to be create dynamically radio button i used following code in javascript in edit.phtml
function createRadio(){
var label = document.createElement("label");
var element = document.createElement("input");
//Assign different attributes to the element.
element.setAttribute("type", 'radio');
element.setAttribute("value",array_resp);
element.setAttribute("name", 'radio');
label.appendChild(element);
label.innerHTML += "Matched Address("+j+"):-"+array_resp;
document.body.appendChild(label);
}
And used button:-
<input type="button" onclick="createRadio()" value="Create radio" />
for calling above function . But it not works.whats wrong in it?please any magento expert give me sugestion.
Thanks in advance.
Demo
Be sure that you are including js function correctly. You can check your browser console for any specific error. Also, check your variables array_resp and j is valid.
I assume your variables like;
array_resp = b, and j = a;
and you can use;
HTML:
JS
window.createRadio = function() {
var label = document.createElement("label");
var element = document.createElement("input");
//Assign different attributes to the element.
element.setAttribute("type", 'radio');
element.setAttribute("value","b");
element.setAttribute("name", 'radio');
label.appendChild(element);
label.innerHTML += "Matched Address(a):-b";
document.body.appendChild(label);
}

Get value of dynamically created textbox using JavaScript

I'm using JavaScript to dynamically add rows to a table, I create some textboxes in each row, I've added an onkeyup event to one of my textboxes:
var myTotal = "1";
var spanTotal = document.createElement("span");
spanTotal.innerHTML = "<input style=\"width:50px\" type=\"text\" name=\"total\" value=" + myTotal + ">";
spanCount.onkeyup = function ()
{
alert(spanTotal.innerHTML);
};
then I add this span (which is rendered as an HTML textbox) to my table row. I want to have value of my dynamically created textbox, but whenever I change this textbox, initial value of this textbox is displayed in alert box (i.e. 1). Initial value of this textbox is "1", but when I change it (for instance type a 0 in textbox), again "1" is displyaed in alert box. I want to have value of my dynamically created textbox, should I give an ID to my span? how should I define spanCount.onkeyup function? where should it be defined so that I can have exact value of this textbox?
I created a jsFiddle. You can get value of input box using childNodes. There are other problems in code you were using spanCount istead of spanTotal.
Modified code:
var myTotal = "1";
var spanTotal = document.createElement("span");
spanTotal.innerHTML = "<input style=\"width:50px\" type=\"text\" name=\"total\" value=" + myTotal + ">";
document.body.appendChild(spanTotal);
spanTotal.onkeyup = function() {
alert(spanTotal.childNodes[0].value);
};​
Below modified code maybe can solve your problem:
var myTotal = 1;
/* object creation */
var span = document.createElement('span');
var input = document.createElement('input');
input.setAttribute('type', 'text');
input.setAttribute('name', 'total');
input.setAttribute('style', 'width:50px;');
input.setAttribute('value', myTotal);
// append each object to respective container
span.appendChild(input);
document.appendChild(span);
/* event handler */
input.onkeyup = function(){
alert(this.value);
}

Commands in Javascript code are overwritten by the last one

I have stacked with my javascript code. In my app I am also using jQuery for faster writing some of the parts.
The thing is that after adding functionality to input files only the one added to the last is working. I found that maybe the reason is this same name of function with this same parameters. So to be sure I added to one my function which I want to use and to the other (I mean the first one) alert with simple text.
This is my code:
newRow.innerHTML = "<a href='#' class='editName'>"+ddList.ddElements[ddList.ddEl.id]+'</a>';
newRow.innerHTML += ' X:<input type="text" id="x'+ddList.ddEl.id+'" name="x'+ddList.ddEl.id+'" size=3 value=0>';
var xField = document.getElementById('x'+ddList.ddEl.id);
xField.relatedElement = newRow;
newRow.innerHTML += ' Y:<input type="text" id="y'+ddList.ddEl.id+'" name="y'+ddList.ddEl.id+'" size=3 value=0>';
var yField = document.getElementById('y'+ddList.ddEl.id);
yField.relatedElement = newRow;
$(xField).blur(function(){alert('Handler for X.blur() called.')});
$(yField).blur(function(){ddList.setObjectPosition(yField,obj,'y');});
if(RegExprText.test(ddList.ddEl.id))
{
newRow.innerHTML += '<br>Kolor:';
var element = document.createElement('input');
element.setAttribute('id', 'c'+ddList.ddEl.id);
element.setAttribute('name', 'c'+ddList.ddEl.id);
element.setAttribute('type', 'text');
element.setAttribute('class', 'color');
element.setAttribute('size', '6');
newRow.appendChild(element);
var myPicker = new jscolor.color(element, {});
$(element).blur(function(){ddList.setColor(element,obj);});
}
var links = newRow.getElementsByTagName('a');
var editLink = links[links.length-1];
editLink.relatedElement = newRow;
$(editLink).click(function(){ddList.deleteObject(obj,newRow);});
So when I have got only X and Y input fields then only Y is active. When I have got X, Y and colorPicker then only colorPicker works.
Interesting thing is that always is working last line of code - editLink.
And I have been trying to change
xField.relatedElement = newRow;
on
newRow.addChild(xField);
It doesn't work either.
Thanks for answers in advance.
First you do
xField.relatedElement = newRow;
And then you change
newRow.innerHTML
which will of course be reflected in the relatedElement.
If you want three different DOM elements, you have to make three different DOM elements, and not just one that you assign to three places and whose content you change three times.

variable as button value in javascript

I will be reading a tag from xml and assign it to a variable, ID.
ID=(x[i].getElementsByTagName("ID-NUM")[0].childNodes[0].nodeValue);
How could I use the variable, ID, as the button value to display?
document.write("<input type = button value = ID style='width:100'><br><br>");
Kindly let me know if I an not clear, thanks.
You'll need to put that variable into the string that you're writing out
document.write("<input type='button' value='" + ID + "' style='width:100%'/><br/><br/>");
Alternatively, if you already have the button object written out, you can use the object model directly:
document.getElementById("idOfButtonObject").value = ID;
document.write("<input type='button' value='" + ID + "' style='width:100;' />
Don't use document.write to insert anything on the page. It's problematic because if you do it after the object model has been constructed, it will wipe out the entire document and create a new one. Instead use the DOM methods to create a button.
var input = document.createElement('input');
input.type = 'button';
input.value = ID; // set the ID
input.style = 'width: 100';
document.body.appendChild(input); // add to page
