Html Code not working properly while generated with JavaScript - javascript

I am trying to impliment the IN Place Editing functionality using JQuery.
Here is the code
editinplace.js
$(document).ready(function() {
//When div.edit me is clicked, run this function
$("div.editme").click(function() {
//This if statement checks to see if there are
//and children of div.editme are input boxes. If so,
//we don't want to do anything and allow the user
//to continue typing
if ($(this).children('input').length == 0) {
//Create the HTML to insert into the div. Escape any " characters
var inputbox = "<input type='text' class='inputbox' value=\""+$(this).text()+"\">";
//Insert the HTML into the div
$(this).html(inputbox);
//Immediately give the input box focus. The user
//will be expecting to immediately type in the input box,
//and we need to give them that ability
$("input.inputbox").focus();
//Once the input box loses focus, we need to replace the
//input box with the current text inside of it.
$("input.inputbox").blur(function() {
var value = $(this).val();
$(".editme").text(value);
});
}
});
});
ButtonClickFunction.js
function ADDRADIOBUTTON(){
//Creating the div Tag
var answer_div = document.createElement("div");
answer_div.setAttribute("class", "answer");
answer_div.id = "answer_div_"+counter;
// Creating the Radio button tag
var answer_tag = document.createElement("input");
answer_tag.setAttribute("type", "radio");
answer_tag.id = "answer_tag_"+counter;
answer_tag.setAttribute("name", answer_div.id);
// Creating the Label Tag
var radio_label_tag = document.createElement("label");
radio_label_tag.setAttribute("for", answer_tag.id);
//Creating the label
var In_Place_Edit_div = document.createElement("div");
In_Place_Edit_div.setAttribute("class", "editme");
var In_Place_Edit = document.createTextNode("label");
In_Place_Edit_div.appendChild(In_Place_Edit);
radio_label_tag.appendChild(In_Place_Edit_div);
// Adding Radio button dot on the div and screen actually
answer_div.appendChild(answer_tag);
//Adding the Label here on the right of radio button.
answer_div.appendChild(radio_label_tag);
// Adding Answer div to the main div
var element=document.getElementById("divid_"+counter);
element.appendChild(answer_div);
}
and the index.php file includes these two JS files along with jquery-1.8.2.min.js
<script language="javascript" src="js/jquery-1.8.2.min.js"></script>
<script language="javascript" src="js/editinplace.js"></script>
<script type="text/javascript" src="js/ButtonClickFunction.js"></script>
What I am trying to do is create a radio button with label besides it and the label can be edited when we click on it. Now the problem here is that when I use the Code
<div class="editme">Please click me!!</div>
directly in the index.html page it works fine but when I try to generate the same line of code dynamically as I shown in ButtonClickFuction.js file it Does not work. What might be the problem ?

After crerating the HTML element dynamically you must bind the click function once more.Otherwise it wont work.Just call the click function after dynamic creation of the
< div class="edttime">Please click me!!.Otherwise click wont work for the newly created div with class edttime.
$("div.editme").click(function() {
//This if statement checks to see if there are
//and children of div.editme are input boxes. If so,
//we don't want to do anything and allow the user
//to continue typing
if ($(this).children('input').length == 0) {
//Create the HTML to insert into the div. Escape any " characters
var inputbox = "<input type='text' class='inputbox' value=\""+$(this).text()+"\">";
//Insert the HTML into the div
$(this).html(inputbox);
//Immediately give the input box focus. The user
//will be expecting to immediately type in the input box,
//and we need to give them that ability
$("input.inputbox").focus();
//Once the input box loses focus, we need to replace the
//input box with the current text inside of it.
$("input.inputbox").blur(function() {
var value = $(this).val();
$(".editme").text(value);
});
}

Dynamically created form called via onclick disappears immediately Javascript

I have dynamically created a button in my Javascript function and called another function onclick, as shown below.
streambtn = document.createElement("button");
streambtn.setAttribute("onclick","createattribute()");
The createattribute() method opens a subdivision within the dynamically created form and this function is as follows.
function createattribute() {
inputval.innerHTML = "Provide a Stream name and click to add attribute-type pairs to yours stream.";
var input = document.createElement("input");
input.type = "text";
input.placeholder="Attribute name";
input.id="attr"+attrID;
input.className = "attr-textfield-style";
inputval.appendChild(input);
//Display the drop down menu
var newDiv=document.createElement('div');
var html = '<select>', attrtypes = typeGenerate(), i;
for(i = 0; i < attrtypes.length; i++) {
html += "<option value='"+attrtypes[i]+"'>"+attrtypes[i]+"</option>";
}
html += '</select>';
newDiv.className="attr-combobox-style";
newDiv.id="type"+attrID;
newDiv.innerHTML= html;
inputval.appendChild(newDiv);
attrID++;
alert("attrname id: "+input.id+" attrtype id: "+ newDiv.id);
}
The inputval is a division within the dynamically created form where the newly created form elements from the createattribute() function will be appended to. But the issue that I'm facing right now, is that though the method is correctly called, the form(dynamically created form) immediately disappears in a split second once the streambtn is clicked. Once it is clicked, it displays the first line "Provide a Stream name and click to add attribute-type pairs to yours stream." in a flash and disappears. Is there a way to keep it onscreen and then hide it depending on any conditions(like after the user finishes entering the data corresponding to that newly opened form-> created via createattribute() method)?
Add type = "button" as <button> without type = "button" will act as submit button and over click of the submit buttopn, page will be unloaded.
streambtn = document.createElement("button");
streambtn.type = 'button';
streambtn.setAttribute("onclick","createattribute()");

javascript: deleting tags of a selected element in a text

I put a tag to a selected element in my textarea and every tag take an id. And I store the element an a table.
But, I want to delete some tags(I have to type of tag "ref" et "point"). And I try this function but, it doesn't work:
function deleteTag(textField, tag)
{
var scrollTop = textField.scrollTop; //For the scroll of the text
var start = textField.selectionStart; //beginning of the selected text
var end = textField.selectionEnd; //End of the selected text
var modif=textField.value.substring(start,end); //The text to modify
// Remove the tag
if(modif.match('[^<]'+tag+'id="(\\d+)">') && modif.match('</'+tag+'[>$]'))
{
var regex;
if(tag=="ref")
{
regex=new RegExp('<'+tag+' id="(\\d+)">');
var opt=modif.match(regex)[1];
document.getElementById("refList").remove(opt-1);
}
regex=new RegExp('<'+tag+'[^>]+>');
modif=modif.replace(regex, "");
modif=modif.replace('</'+tag+'>', "");
}
textField.value=textSup+modif+textInf; //We modify the text inside the text area
textField.scrollTop=scrollTop;
}
And the button have this code:
<button onclick="deleteTag(textAreaId, 'ref')"> Effacer
By the way I'm beginner in javascript
if(modif.match('[^<]'+tag+'id="(\\d+)">') && modif.match('</'+tag+'[>$]'))
maybe you need an extra space in the regex:
if(modif.match('[^<]'+tag+' id="(\\d+)">') && modif.match('</'+tag+'[>$]'))

How can I prevent users input to be cloned in the appended input box in javascript

When I insert some thing in the input box of module 1 and click add module button to clone the required elements that I need it clones also the inserted input I've tried to prevent that using event.preventDefault(); but it's still copying the input box with the inserted input from module 1 however, I can't clear it using the clear button that is located in the input box moreover the appended select options doesn't work and when I select an option it doesn't change.
Here is my demo of what's happening:-
http://jsfiddle.net/0ojjt9Lu/6/
and here is my javascript code:
$(document).ready(function(){
$("#Sadd").click(function(event) {
event.preventDefault();
var lastId = $("#modules h1").length;
var $newLabel = $("#module-1-label").clone();
var $newSc = $("#module-1-scredit").clone();
var $newSgrade = $("#module-1-sgrade").clone();
$newLabel.html("<h1>Module " + (lastId+1) + ":</h1>");
$newSc.find("label").attr("for", "Sc"+(lastId+1));
$newSc.find("input").attr("name", "Sc"+(lastId+1)).attr("id", "Sc"+(lastId+1));
$newSgrade.find("label").attr("for", "Sgrade"+(lastId+1));
$newSgrade.find("select").attr("name", "Sgrade"+(lastId+1)).attr("id", "Sgrade"+(lastId+1));
$("#modules").append($newLabel, $newSc, $newSgrade);
});
$("#Sremove").click(function() {
var lastId = $("#modules h1").length;
if(lastId > 5){
var lastLi = $("#modules h1").last().closest("li");
var lastLi2 = lastLi.next("li");
var lastLi3 = lastLi2.next("li");
lastLi.remove();
lastLi2.remove();
lastLi3.remove();
}
});
});
Use .val("") on the new input to clear the data in on the clone
or do $(clone).find('input').val(""); if there is more than one input
In your case with the select box you need to add the following lines
After you declare (or on the same line) the variables
var $newSc = $("#module-1-scredit").clone().find('input').val("");
var $newSgrade = $("#module-1-sgrade").clone().find('option:selected').removeAttr('selected');
$newSgrade.find('option[value="-1"]').attr('selected',true);
Edit: Had to handle the reselection of the select due to default value being "-1" however you may need to look at the cloning of this select element. Perhaps on the page have the blank question hidden and just clone that.

Error message not showing and hiding depending on if else statement

I have a function that loops through all of the inputs of my form and checks if they are filled or not. If the field is blank, it makes that specific input pink and returns false.
I'm trying to add a "Field Required" message underneath the inputs that are not filled. So i coded an extra table row after each one, with a div that holds the error message. The css for the div is set to "display:none" on page load.
Right now my function is showing "required" for every input and not just the ones that are blank, but the pink coloring is still working correctly.
How do I get the "required" div to show and hide correctly like the pink coloring does?
checkinputs = function (blockOne,blockTwo) {
inputGood = true;
blOne = $(blockOne);
blTwo = $(blockTwo);
blInput = [blOne,blTwo];
for (x = 0; x < 2; x++) {
var validators = blInput[x].find(" [id$='RequiredIndicator']").parent().parent('tr').find(':input:not(:hidden)');
var notAllFilled = validators.filter(function(){
var myInput = $(this); //.parent().parent('tr').find(':input');
var filledVal = myInput.val();
var isFilled = $.trim(filledVal).length;
if (isFilled) {
$(this).css('background-color', 'white');
$(this).closest('div').find('.required').hide();
$(this).parent('td').prev('td').find('span').text('*');
}
else {
$(this).css('background-color', 'pink');
$(this).closest('div').find('.required').show();
$(this).parent('td').prev('td').find('span').text('*');
inputGood = false;
}
return isFilled;
}).length;
var inputCount = validators.length;
};
if( !inputGood ){
$('#errorAlert').append('<span style="font-weight:bold;">"Some required information is missing. Please complete the missing fields below."</span>' + '<br><br>');
$('#errorAlertTwo').append('<span style="font-weight:bold;">"Some required credit card information is missing. Please complete the missing fields below."</span>' + '<br><br>');
}
return inputGood;
};
HERE IS A FIDDLE OF THE ISSUE:
http://jsfiddle.net/RNMM7/
Your issue is almost definitely your line to show the div:
$(this).closest('div').find('.required').show();
What this line does is:
Starting at your $(this), it finds the nearest ancestor [including $(this)] that is a div, going up the DOM tree
Finds all elements with class 'required' under that div, and shows them.
Without seeing how your HTML is structured, my guess is that the nearest div element up the DOM tree encompasses all your .required elements. You'd need to replace the 'div' in that statement with an element lower in the DOM tree that would only encompass your $(this) and the one .required element you want to show.

How to make 'return false' prevent execution of successive functions in an inline onclick event handler?

I have the following input field with an inline event handler containing multiple functions. I was hoping that if reqField() returned false the remaining functions would be cancelled, but this is not happening.
All that happens is that reqField() is terminated early and if there was a default action for an input field, it would be prevented. Is there anyway to achieve the result I'm after (termination of the remaining functions).
By the way, I can't just remove them from the onclick before returning false because they need to remain in place for the next onblur event.
function getnDisplayTextInputBox(id) {
var s = document.getElementById(id);
s.setAttribute('onclick', '');
var obj = getDataAttribs2Obj(id);
var str = getParamStrFromDataObj(obj);
s.innerHTML = "<input type=\"text\" data-param=\""+obj['param']+"\" id=\"edit\" value=\""+htmlentities(s.innerHTML)+"\" onblur=\"return reqField(this); postData('"+obj['sendtourl']+"', '"+str+"&spanid="+id+"&newVal='+this.value, 'replaceTextTextInputFieldWithValue(resp);', '','');\">";
document.getElementById('edit').focus();
}
The above function replaces text in a span with an input field populated with the same text, when a user clicks on the original text. They can then edit the text, which is send to the server and saved onbur.
Some of the spans have an attribute data-param='required' and if so, the reqField() will require that the field is not empty and will return false if it is (after alerting the user to the problem with an alert box). Obviously, I don't want the next function in-line to fire, sending the empty field to the server for saving, or the one after, which swaps out the input box for plain-text in a span.
Try this
function getnDisplayTextInputBox(id) {
var s = document.getElementById(id);
s.setAttribute('onclick', '');
var obj = getDataAttribs2Obj(id);
var str = getParamStrFromDataObj(obj);
s.innerHTML = "<input type=\"text\" data-param=\""+obj['param']+"\" id=\"edit\" value=\""+htmlentities(s.innerHTML)+"\" onblur=\"if(this.value==''){return false;}else{return reqField(this); postData('"+obj['sendtourl']+"', '"+str+"&spanid="+id+"&newVal='+this.value, 'replaceTextTextInputFieldWithValue(resp);', '','');}\">";
document.getElementById('edit').focus();
}
