If I code JavaScript as if it were C code with respect to the use of semicolons, are there any caveats? I understand that I will be typing a few more semicolons than absolutely needed.
How to display an alert message with a scroll bar attached?
If this is not applicable, then how to display a popup message with a scroll bar, which acts completely as an alert message in its behaviour, meaning that the user can not act on the page except when he confirms the alert?
how to get the alert box to display in text instead. So when the user clicks on the submit button instead of an alert box, the result would display below the button in text instead of an alert?
<script type = "text/javascript"> function validate (form){ var hrs=(form.hrs[0].checked)? form.hrs[0].value : form.hrs[1].value;[code].....
I have been being banging my head against this for hours. I have an iframe that contains XML. All I want to do is display the XML content in a JavaScript alert. Here is what I have figured out.
This code retrieves the XML document object from the IFrame.
So I tried a simple alert on this and I receive the message:
So I think at this time, I have an XML Object.
So I tried this code:
Code:
Running this code, all I get back is an empty alert message which has me confused.
I have a classified listing application (php) that shows an alert message on the main page to let the user know if there was an error, if the listing was entered, if a required field was left blank, etc.
the alert msg. displays whenever the page is loaded. However, if someone navigates with the forward or back buttons in the browser, or reloads the page, the alert message displays again.
I am pulling my hair out for a solution that shows the alert only once and then does not show an alert again until a new message is generated.
I tried to display an alert window (avoid pop up since some users blocks it and hence not displayed on onload event in body) But it is not displayed properly like popup window.
So, I am in a Web Development class right now for my liberal arts science credit. We are on a lab dealing with JavaScript and half of it is making the values of some check boxes and stuff show up when the user clicks a "Display" button. I'm not sure I'm explaining it well. Here's the lab:
# In lab 6 you wrote a JavaScript function that displayed the name and email entered from the form. Extend that function to display all of the information the user entered in the form (name, e-mail, region, special interests, interest level, and comments). See if you can nicely format what shows in the alert message. The following hints should help:
1. The first step is to make sure that each GUI field has an id attribute set. For example the name field might have id="name". Remember, every id value must be unique. Two radio buttons will have the same name attribute value, but their id attributes must be unique. You need to do this so JavaScript can find the tags using the document.getElementById method.
2. To display your checkbox information, you will need to include logic as described in the following steps. Once you do this, do the same thing for the radio buttons.
1. Assume you have a checkbox with id="cherokee". Of course, your id attributes will likely have different names. The general steps will be the same, but substitute your names where I'm using "cherokee".
2. The following statement creates a Boolean value (true, false) that determines if the user checked the cherokee checkbox. The checked property in checkbox and radio button objects gives this information.
I am trying to get a checkbox to display an alert when the user clicks the checkbox for "other". Then if they click it again to unchedk it, it should not display the alert again. I keep getting an message that says not an object. Can anyone help me out with this? I have copied the code below for the checkboxes and the code that is in my .js file....
I'm trying to run through the simplest tutorials on jquery and for some reason I can't get any of the jquery code to work.I've downloaded jquery and I've made sure that this file is in the same directory as jquery-1.3.2.js.This is the code taken from the tutorial:
I need to display alert when I close the browser window. Now I am using the following code to display the alert. But the alert is getting displayed even I click on any links. But the alert should not displayed when i click the link.
I'm relatively new to jQuery, and I don't understandy why the following doesn't work. Hopefully, you can enlighten me. I declared a variable: var currHive = $("#masterHive") .find("div.currentHive"); Now I want to see if the query returned the correct element id. So, I tried each of the alert messages shown below, one-at-a-time. This is the strategy I am using to verify the code; i.e. do something, then tell me what I did.
Note: I have successfully used --- alert($(this).attr('id')); --- in an experiement to tell me which button was clicked, in a statement using the .bind() method.
The following code returns the width and height as: undefined in the alert. I can`t see what i am doing wrong here. I would like the width and height of the chosen image to be displayed in the alert.
<html> <head> <script type="text/javascript" language="javascript"> function getImageSize() {
I need to display alert when I close the browser window. Now I am using the following code to display the alert. But the alert is getting displayed even I click on any links. But the alert should not displayed when i click the link. [code]...
I got a problem with a standard if... else if sentence. Each one works alone, (ie. putting a /*..*/ around one of the conditions)but by combining them, only the first one triggers. The code :
function sjekk() { if (window.document.info.organisasjon.value =='') { alert('hey!'); return(false); } else { if (window.document.info.check_feste.checked == false) { var answer = confirm('Continue?'); if (answer) { return (true); } else { return(false); } } } }
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything.
In my functionality, I need to replace all the apostrophes(') present in the sentence with double apotrophes('') so that it can be stored in the database. I am able to replace the first apostrophe with indexOf() and replace() methods.
How do I replace the other apostrophes present in the string?
Does anyone know of an easy way, using javascript/jscript/jquery only, to get the first sentence of any Wikipedia article?
I've tried using ajax to grab all the html and then narrow it down using a couple of split() functions, but not every article is the same, so I don't think I can do it that way.
I am taking a Javascript class and the teacher assigned this: Quote: Write a script that uses a random number generation to create sentences and name it sentences.html. Use five arrays of strings called: uppercase article (uarticle), noun, verb, lowercase article (larticle), and preposition. You will need to use the correct case for the article arrays. Create a sentence by selecting a word at random from each array in the following order: uarticle, noun, verb, preposition, larticle, noun. You can find examples of generating random numbers in both Fig. 8.6 (dice-rolling) and Fig. 8.7 (random image) of Chapter 8.
The arrays should be filled at minimum, as follows: the article array(s) should contain the articles: the, a, one, some and any. The noun array should contain the nouns: boy, girl, dog, town and car. The verb array should contain the verbs: drove, jumped, ran, walked, and skipped. The preposition array should contain the prepositions: to, from, over, under and on. If you would like to add more words, adjust the arrays appropriately.
