Get Return Value Of Function For Deletion In Database
Mar 19, 2011
I have this code
<TR id="tr1" onClick="var ret_val = clickedfun(this.id)" />
and this javacript code
<script language="javascript">function clickedfun(tid) {var elemento = document.getElementById(tid);if(confirm("Tem a certeza que quer remover esta fila?")){elemento.style.visibility='hidden';var numero=tid.substring(2,tid.length);return numero;}}</script>;
I want to get the return value of the javascript function to use in database for deletion of that value. I am using jsp and java classes.
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.
To confirm that a CMS user really wants to delete a record, I have added some Java Script that was originally intended to confirm if a user wants to visit a new web page that takes a long time to download. The script provided two location.replace() options: 1) to visit the new page or 2) to return to the previous page. I want to modify it so that the options are 1) to continue on to the following deletion script or 2) reurn to the previous page. How do I set up option 1) to do this in the following script? Probably something else than location.replace().
Right now I have option 1) set to direct the user to the same deletion page where this script resides. But this will just loop the user back thru the same JavaScript. Again, I want the first option to just allow the user to continue on thru the rest of the deletion script. Code:
I have this C# code that is connecting to database and creating a array(list)
Code:
I'm trying to pass it to a javascript function so I can then pass it to a silverlight page so I was able to create this easy javascript that show a aleart box on startup of the list(array)
Code:
But I want to do something like this and can't get it:
Having problems with my add button, it works . . . when it wants to. Its OK when adding but when trying to add after deleting it gets moody and doesn't work. I didn't use a loop but there's a counter for the sake of the IDs cause I will be connecting a database to it.
I hava e java script fr confrmation of record deletion on server side in asp.net
In the button event i have a query for redord deletion
I need to delete the records if u use the return keyword the record doesnot get deleted but if i remove the return keyowrd the record gets deleted even if CANCEL is clicked
Of course, I make code for marker add and move, but how do I can make deletion option for marker? And how do I can make automatic route creator from marked point A to marked point B?
I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?
i've got a function which makes a call to the database( via jquery $.post) to check if a username already exists. All the data I get back is fine and both the conditional statment works as intentded. I just can't get the function to return a value to the other function that calls it. Could this be something to do with the scope.
Afternoon all, Have a pretty simple function, that requests a number to be entered. I want to return that number, but i seem to be typing something wrong in the return value.
function newFunction(a, b) { var newArray = new Array(a); for (var i = 0; i < 5; i = i + 1)
I am populating a field on my page using a php include. I am asking javascript to update another element with that field's value. The value written to the select input box is Ƈ:Any Provider'. The process works fine in Firefox. In IE6 it does not write. the value nor does it throw an error. What am I doing wrong?
function postthis(){ var provider = document.inputForm['provider'].value; var report = document.getElementById("status"); var message="The Value of Provider Block is: " + provider; report.innerHTML = message; }
In firefox, "The Value of Provider Block is: 1:Any Provider" is written in the report element. In IE6, "The Value of Provider Block is : " is written in the report element.
I know the answer must be yes, but I am really having a hard time figuring this out. I have a simple script below, that calculates age (I know I need to do some more work). I want to redisplay the value returned from the function. It works OK, because the result displays correctly in the alert. Code:
I have a form and a submit button .on clicking submit button function validate call.this function call another function (say func) .this func function vallidates some input and return true or false value to the validate function this then return true or false value to the submit button .I want that func directly return true or false to the submit button.
I have a multiple choice quiz that works fairly well. However, instead of it presenting "End of Quiz" message when last question is completed I need it to take the user back to the beginning (question 1) but with no indication to the user that this has been done. How can I adjust the code to have it do this?
<script language="JavaScript1.1"> var whichone=1 var tempmn=document.quiz.thequestion function generatequestions(){ document.quiz.theresponse.selectedIndex=0
I want to pass a javascript function's return value, to an anchor tag's href parameter i.e. <a href>
Suppose I have a function called getTrackingCode( ) that contains a value "testSite" <script language = "JavaScript"> function getTrackingCode( ) { return "testSite"; } </script>
Now I want to pass this function's value to anchor's href, I have attempted these:
I have a desire to include more than one return statement in a function I have written so that when it has found the solution to a hit-testing series of conditionals, it returns the solution. The desire is to avoid further hit-tests when solution has been found. I've always felt that more than one return statement in a function is poor style, since it may lead to false execution of a function - by way of a later code edits - making a mistake by forgetting the multiple returns. My function is short and maybe the optimisation exists only in my head but are there serious reasons why one should not have more than return statement? This JS code executes in the Quartz Composer framework and has nothing to do with we programming (context (-:)
Here it is with three returns, it 'works' and I could replace all the break statements with return statements to finish optimizing: //Test for y inside range for all quads ( Quad is defined by 4 points in a row in the list is a quad ie. list[0-3], list[4-8], //Test along the unit numerals (_N) and also the 'Revert Patch' button if (y >a[0]["Y"] && y <a[2]["Y"]) { for (i=0; i <37; i+=4) { //Log("DDDDDDD "+i+" X:"+x+" Y:"+y); .....
I've been reading up on Javascript. I read that you can use:
document.write("<h1>My Test</h1>"); So I wrote a little script: <script type="text/javascript"> var choices = new Array(); choices[0] = "<img src=\"crush.png\" />"; choices[1] = "<img src=\"curse.png\" />"; choices[2] = "<img src=\"endless.png\" />"; choices[3] = "<img src=\"eyes.png\" />";
My function the_magnitude() takes in values from 4 different asp:textboxes. The textboxes "easting" and "northing" contain numbers that don't change, but the textboxes "east" and "north" contain numbers inputed by the user, and the function returns "error" as a value to be put into another textbox that we'll call "error box". So what it's suppose to do is when I update the information in either "east" or"north" it will update, on change, the number in the "error box". It kinda works.My problem is that if the number is a value that changes the style to red, #ff0000,in the function it wont update the "error box" and it just leaves a red zero that is a default number in the box. The only way I can get the number to change is if I end up with a number less than 200, which would make the text green.I'm pretty sure it's a problem with my javascript.here is my function
<script type="text/javascript"> function the_magnitude(easting, east, northing, north, error) { var a = easting.value;
I have a function which has two URLs that need to be posted via php onto a database. I had them as individual functions and they work fine but ideally I would like them to be done in the same function. For example, like the following... if (request !== null){ request.onreadystatechange = loginsuccess; //function to check RS=4 & Status = 200. request.open("GET", urllogonsubmit, urlrecieveemail,true); request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); request.send(null); }
I am relatively new to js, but I did think I was starting to get the hang of it. Then this happened...
I have a form with an onsubmit event handler: <form id="uploadForm" method="post" action="..." onSubmit="checkDates()">
The event handler does some minor validation, then returns true or false:
function checkDates(y, m, d) {
if (endDate.getTime() >= startDate.getTime()) return true;
alert("Start date must precede end date"); return false; }
(The arguments to the function are used when it is called elsewhere, not as onsubmit.)
I also have a library class which needs to process the form submit, so it hooks onsubmit like this: MyClass.setOnSubmit = function(listId) { var list = document.getElementById(listId); var form = list.form;
var f = form.onsubmit; if (typeof f == "function") { form.oldOnSubmit = f; form.onsubmit = function(){ var ok = this.oldOnSubmit(); if (ok) return MyClass.onsubmit(listId); else return false; }; } else form.onsubmit = function(){MyClass.onsubmit(listId);}; }
My problem is that the value returned from oldOnSubmit and stored in ok appears as 'void'. This happens in IE 6 and in FireFox 1.07. Can anyone explain what's happening?
function getParentElementByTagName(child, TagName){ var cn; if (child.parentElement){ cn = child.parentElement; if (child.parentElement.tagName == TagName){ return cn; }else{ getParentElementByTagName(child.parentElement, TagName); }}}
although it finds the element, the function returns null ( on the line 'return cn', cn is not null though). Is my algorithm wrong ?
I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"
