uncaught error NOT_FOUND_ERR DOM Exception 8 - javascript

So I am deleting all the contents under a particular div and adding a message content. However, javascript throw the following error after the finish:
Uncaught Error: NOT_FOUND_ERR: DOM Exception 8
Here is the code where it is executed
new Ajax.Request("profileThis.php",
{
method:'post',
parameters:{title:title, review:review, userId:userId, category:category, categoryId:categoryId},
onSuccess:function(ajax)
{
alert(ajax.responseText); // this is just for debugging purposes
var message=ajax.responseText;
var divMessage=document.createElement("div");
divMessage.style.color="rgb:(105,105,105)";
divMessage.innerHTML=message;
while($("reviewSheet").hasChildNodes)
{
$("reviewSheet").removeChild($("reviewSheet").lastChild);
}
$("reviewSheet").adopt(divMessage);
},
onFailure:ajaxFailure,
onException:ajaxFailure
});
People commented that the problem was with how I assigned divMessage to reviewSheet. I tried both adopt and appendChild but none works.
A little help would be appreciated.

divMessage.style.color="rgb:(105,105,105)";
should be
divMessage.style.color="rgb(105,105,105)";

Is the problem that you are calling the method hasChildNodes() on a jQuery object? I'm not sure what $("reviewSheet") is supposed to be, but wrapping a string in $() makes it a jQuery object which I don't believe will work with regular javascript methods. If "reviewSheet" is the id of an element you could do something like
node = document.getElementById('reviewSheet');
then you could go into your while loop.
while (node.hasChildNodes()) {
//the rest of your code here
}
Oh also you need to put the parenthesis after hasChildNodes() to return a boolean value.

TypeError: elem[prop] is not a function in Webdriveio

TypeError: elem[prop] is not a function
E2E testing in webdriveio. I want to click a button inside an iframe.
let iframe = browser.$('#fullmessage')
browser.pause(1000)
browser.switchToFrame(iframe)
browser.setTimeout({ implicit: 10000 })
let clickAgree = $('a[class="button is-success"]')
clickAgree.click()
browser.switchToParentFrame()
browser.pause(3000)
I was facing same error and when debug more using REPL found that the issue could be due to 2 reasons:
selector is returning array of elements and so it was not able to call the method used.
the method being called on element does not supports.
For example with following code:
$('.some_class').$$('input').getValue();
was getting error - Uncaught Error: elem[prop] is not a function. Using $('.auto_test_class').$$('input')[1].getValue(); works. But its better to use some Id or xpath.
Hope this might be useful for someone facing same issue :)
Hi i faced with the same problem, but in async. The reason is that you need
to await already defined element as parameter:
get iframe() { return $('.iframe'); }
await browser.switchToFrame(await this.iframe);
Because switchToFrame works only with element, not with promise.
Maybe for someone it will be useful.

Uncaught TypeError: Cannot read property 'value' of null, need some direction

I have been trying to figure out this particular problem in my developer tools, but I've had no luck thus far. I have an error on one of my js files that says
Uncaught TypeError: Cannot read property 'value' of null
The following error refers to the 1st variable of dt_version below. The particular thing is if I comment out the first line of code. I get the same error on the following variables of offload1 and offload2. The variable is a number that I am trying to get passed over. I run this function on my body when the page loads...onload=updatetotal();
function updatetotal() {
var dt_version = document.getElementById("dt_version").value-0;
var offload1 = document.getElementById("capacity_offload1").value-0;
var offload2 = document.getElementById("capacity_offload2").value-0;
var offload3 = document.getElementById("capacity_offload3").value-0;
}
If a run an if statement looking for document.getElementByID("dt_version");...it defaults to false..so its not being carried over though on the previous page, I can see its input fine with the value in it. What am I missing here guys?
This error means that the id dt_version does not exist. Check your html to make sure it is there:
var dt = document.getElementById("dt_version");
if (dt){
// do your stuff
}else {
console.log("dt does not exist")
}
Another cause for this error may be- as you are calling the javascript function on page load there is a possible chance that your control is not yet completely rendered to the page. A simple solution is just move that control to the beginning of the page. If it doesn't work then an reliable solution is, call the function inside jquery $(document).ready().

Undefined variable error that shouldn't be a variable

I've made a piece of code in jquery that assigns a href attribute to a variable. Here's that code:
$('#reactions' + i).attr('href', 'javascript:comments ('+entry.url+','+i+');');
This should assign a call to the javascript function comments. Now I want to use that call on a jquery mobile button, like this:
document.write('Reactions');
But doing this gives me a in FF and Chrome. This is the error from FF±
Uncaught exception: ReferenceError: Undefined variable: i_heart_chaos_ihc_after_dark_independence_day_through_a_bullhornthis_is_what
Error thrown at line 1, column 0 in javascript:comments (i_heart_chaos_ihc_after_dark_independence_day_through_a_bullhornthis_is_what,1);:
comments (i_heart_chaos_ihc_after_dark_independence_day_through_a_bullhornthis_is_what,1);
In this, i_heart_chaos_ihc_after_dark_independence_day_through_a_bullhornthis_is_what is the value of entry.url.
I'm just not getting why this error appears, as far as I know, everything should work.
I know that there are questions looking similar to mine, but I couldn't figure out the answer. If you want to see the whole source, it's here.
Surround entry.url with quotes:
$('#reactions' + i).attr('href', 'javascript:comments ("'+entry.url+'",'+i+');');
The best way to fix the issue is to do it the "jQuery way". Instead of adding a href attribute that executes JavaScript, add a click event:
$('#reactions' + i).click( function() {
comments( entry.url, i );
});
Similarly don't use document.write() but add elements to the document using jQuery functions.

JQuery: .hide() is not a valid function

Firebug is complaining about this line:
$("#original-description").text(response['course']['original_description']).hide();
Do I have a syntax error? Looks fine to me.
More context:
bindOnSuccess($('#course-search'), function(response) {
if (!response) {
$("#system-status").text("Sorry, no course could be found for that search.");
}
else {
$(".dept-code").text(response['course']['dept_code']);
$(".course-number").text(response['course']['number']);
$(".course-title").text(response['course']['title']);
$("#div-original-description").show();
$("#original-description-teaser").show();
// error here
$("#original-description").text(response['course']['original_description']).hide();
$("#td-required-for").text(response['analysis']['cRequiredFor']);
}
});
response is a JSON object. Could this problem be caused by invalid subscripts?
Firebug's error is:
$("#original-description").text(response.course.original_description).hide is not a function
The other answers are pointing out incorrectly - .text() returns the jQuery object. You are probably referencing an undefined property. I can replicate this:
$('<p>').text(undefined).hide()
Make sure you are referencing the right property in the JSON.
TypeError: $("<p>").text(undefined).hide is not a function { message="$("<p>").text(undefined).hide is not a function", more...}
If you want to query the object live you can simply do
window.o = response in your callback function and just play around with it in Firebug console.

variable assignments using jQuery failing in Safari?

I'm using jQuery 1.3.2 and it's breaking under Safari 4 for mysterious reasons.
All of my javascript references are made right before the tag, yet with the following code:
var status = $('#status');
status.change( function(){ /* ... */ } );
The following error is displayed in the Web Inspector:
TypeError: Result of expression 'status.change' [undefined] is not a function.
However the error is not encountered if I eliminate the variable assignment attach the change method directly like so:
$('#status').change( function(){ /* ... */ } );
Why? I need to use variables for this and several other findById references because they're used many times in the script and crawling the DOM for each element every time is regarded as bad practice. It shouldn't be failing to find the element, as the javascript is loaded after everything except and .
Try changing the variable to something other than "status."
It's confusing your variable with window.status (the status bar text). When I typed var status = $('#status') into the debugging console, the statusbar changed to [Object object]. Must be a bug in Safari.
If you put the code inside a function, so that status becomes a function-local variable, it should work.
It's standard practice in jQuery to wrap things in a
$.onready(function() {
});
This makes sure the DOM is loaded before you try to manipulate it.
