JavaScript - Onblur Event For A Text Inside Logic:iterate
Hello all,
As this is an active javascript programming forum...i'm really hoping i'll get a solution for my problem...please help me out.... I have a html: text inside a logic:iterate block like this.. <logic:iterate name="AllocationsForm" property="newSearchAllocations" id="allocations" indexId="myindex" > <html:text name="allocations" property="newStartDate" indexed="true" onblur="allocationTest(this, " + myindex + ");" /> </logic:iterate> i want to write a onblur event for this text field inorder to validate it. Is it the correct way i wrote or something i need to make a change in the above code inorder for the javascript to work. Can we really able to write a onblur event for a indexed text field that is inside a logic:iterate block. please let me know. Thanks in advance. Similar TutorialsRealizing that form input placeholders aren't universally recognized among browsers, I began changing all of mine using onblur and onfocus handlers instead. As an example, I used the following code, which works in most cases: Code: <input type="text" name="example" maxlength="5" value="Example" onblur="if(this.value=='') this.value='Example';" onfocus="if(this.value=='Example') this.value='';"/> At first, I coded all of the inputs without a value attribute. But, when the page initially loaded, the fields would load empty, and the value/placeholder wouldn't appear until the field had been "focused" and then "blurred" again. Adding the value attribute seemed to correct that problem, again, for the most part. I have some text fields that appear only after I select a particular radio button or select option. Problem is, when the radio is clicked, the field appears, but even with the value attribute in place, the field appears void. I'm not sure what is different, or what I'm doing wrong. Here's the javascript code with the radio button (note:everything works except that the "placeholder" doesn't show when the field first appears): Code: function showfield() {
document.forms[0].otherRelation.value = "";
document.getElementById("newBox").style.display = "none";
var r = document.forms[0].relation;
var len = r.length;
for (var i =0; i<len; i++) {
if (r[i].checked && r[i].value == "Otherrelation" ) {
document.getElementById("newBox").style.display = "inline";
}
}
}
<input type="radio" name="relation" value="Otherrelation" onclick="showfield()"/>Other
<span id = "newBox" style="display:none">:
<input type = "text" name="otherRelation" size="35" value="Your Relationship" onblur="if(this.value=='') this.value='Your Relationship';" onfocus="if(this.value=='Your Relationship') this.value='';"/>
</span>
Thanks for any help. Sorry so long. Hi, I have a problem in javascript, where entering a value in the textbox during onblur I am doing a refresh to bring in the updated records from the DB , before the on blur refresh is completed if the user clicks the search button (onclick) during the first click nothing is happening as the refresh is still going on. During the second click when the on blur refresh is completed it will open a popup. The problem here is I am unable to disable/inactivate the search button untill the refresh is completed as well as I dont have any control over the refresh time as well. This is like already an event is in progress and where we are invoking another event which is not having any effect. In such case how i can handle this scenario? Thanks. I have an onfocus event that makes a textarea large and then an onblur event that sets it back to a smaller textarea. If I click the textarea the onfocus event is triggered but if I go straight to submit the form the onblur event is triggered and the form is not submitted unless i hit submit twice. How can i get the form to submit? Can i put an "if" statement in the onblur event to see if the form is being submitted then just submit the form otherwise run the onblur event? Code: <style type="text/css">

Hi everyone, The following code has an onblur event in the input fields so that if someone clicks out of the field without typing something in it, the original label, ie. 'First name' is reinserted into the field. The field is also being validated by some php code, however the onblur event creates a problem because the form still submits even if a name isn't typed into the field. It's assuming that 'First name' is an entry and therefore isn't validating it correctly. It was suggested that on the submit event of the form, there would be a function that checks if the value is First Name then return false, but then otherwise return true. As my javascript skills are very basic, I wondered if someone could help me with this code to solve this issue? Appreciate any help. Code: <input id="firstname" name="firstname" type="text" value="First name" onfocus="if (this.value == 'First name') this.value=''" onblur="if (this.value == '') this.value='First name'" />
<?php
if (ValidatedField('index_965','index_965')) {
if ((strpos((",".ValidatedField("index_965","index_965").","), "," . "1" . ",") !== false || "1" == "")) {
if (!(false)) {
?>
<span style="color: red"> First name is required </span>
<?php //WAFV_Conditional index.php index_965(1:)
}
}

Sorry I just realized this should have been in server side... I'm trying to create a list of twitter users with a follow button next to each user. The user names are being pulled from a mysql database. Here's the code I have so far. I can get a list of user names from my database, put it into an array and I can replace the user name in the first follow button. I need to sequentially replace the $row variable in the script at the bottom so the follow button points to the users account each time it iterates through the array? I'm stuck on how to iterate this so that I get a list of all the users in the array with a follow button next to each user name. Any help or ideas would be greatly appreciated! I'm stuck and on a deadline. Code:
<?php
// Connect to database server
mysql_connect("localhost", "root", "") or die (mysql_error ());
// Select database
mysql_select_db("tewxadb") or die(mysql_error());
// SQL query
$strSQL = "SELECT * FROM users";
// Execute the query (the recordset $rs contains the result)
$rs = mysql_query($strSQL);
// Loop the recordset $rs
// Each row will be made into an array ($row) using mysql_fetch_array
while($row = mysql_fetch_array($rs)) {
// Write the value of the column username (which is now in the array $row)
echo $row['username'] . "<br />";
}
// Close the database connection
mysql_close();
?>

In this program i attempting to iterate through an array using the charAt () function and then store these element positions in a new array called elementPositions. The user selects a flightDestination from the flightDestinations array which is stored elsewhere, and what my program needs to do, is find all the array elements positions where the same flight destination name occurs in my array. I then need to store these positions so i can use them elsewhere, and i'm pretty sure i need to use charAt() but i think my syntax may be wrong - contained in the for loop. var yourDestination = readTheDestination(); var title = "<B>" + "You asked about Flights to " + "<B>" + "<BR>"; var flightInfo; var solution = ""; var empty = "Please choose a destination city from the Destination menu and then click Find Flights again."; var elementPositions = new array(); for (var i = 0; i <= 25; i ++) { flightInfo = flightDestinations.charAt([yourDestination]); if(yourDestination != "Choose your destination") { solution = flightInfo + "<BR>"; } else if (yourDestination == "Choose your destination") { solution = empty; } } displayMessage(solution); Hello all, and thank you for your coments, I want to preserve a 16/9 aspect ratio to the window after any resize, making the width a function of the height. As I have a window.resizeTo() inside the window.onresize event function, the infinite loop is served. How may I quit it? Code: <html><head><title>Title</title><script languaje="javascript">
const c_ra=16/9;
window.onresize = function WindowReSize() {
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
// myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
// myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
}
myWidth = Math.floor(myHeight*c_ra);
window.resizeTo(myWidth,myHeight); // ** CAUTION resize event in a onresize event handler !
};

I have a question about proper syntax in iterative functions. I want to compare one master array to a large set (180+) of other arrays. The large set of arrays to be compared are systematically named (scorespec1, scorespec2, scorespec3...). Each comparison will be made not one-to-one but through an algorithm and then have the results stored in another set of arrays that are also systematically named for later query. I not worried about getting the algorithm right just yet. I'm just not sure of the proper syntax to iterate through my arrays. For instance, this is but one of the syntax structures I have tried but failed to get working: Code: for (i=01;i=186;i++){
if (scorespec+(i)[04]=unknownspec[16]){
resultarray+(i)[01]=true;}
else{
resultarray+(i)[01]=false;}}
My main problem here is I don't know how to structure the syntax to include the counter variable in my for-loop in the variable name. I've tried a variety of different syntaxes in addition to what I show above and it just doesn't seem to work right. What syntax should I be using? I wish to get the values for the 3rd and 4th cell of each row where these contain drop down menus. I've tried various ways but my code doesn't seem to iterate through rows of a table. I can get the values for the first row, but not the rest. There's isn't a fixed row size for the table as the user will be able to add and delete them. I've put the values in separate arrays but instead of the array containing say [10, 20] it contains [10, 10] as it just duplicates the first row's values. Here's my code that I have so far: Code: function calculate(){
var len = document.getElementById(arguments[1]).rows.length;
var cMenus = [];
var gMenus= [];
for(var j = 1; j<len; j++){
for(var i = 2; i<arguments.length; i++){
var c = document.getElementById(arguments[2]);
var g = document.getElementById(arguments[3]);
cMenus[a] = c.options[c.selectedIndex].value;
gMenus[a] = g.options[g.selectedIndex].value;
}
a++;
}
<button type="button" onclick="calculate('text','course', 'credits', 'grade')">Calculate</button>
HTML Code up to the first dropdown menu: Code: <table id="course" summary="add/remove course details" width="350px" border="1">
<tr>
<td><input type="checkbox" name="tick"/></td>
<td><input type="text"/></td>
<td>
<select name="credits" id="credits">
<option value="10">10</option>
<option value="20">20</option>
</select>
</td>
</td>
<select name=....
I've tried adding j to the arguments or putting it in "[]" but nothing seems to work. I don't think the platform I'm using supports jquery, so help would be really appreciated for using javascript, thanks. [This is an updated question from my previous thread as I was unable to edit or delete my question] I'm very inexperienced with Javascript, but want to use the onclick event to change an image to text. I'm working on a directory type website and want users to have to click on the image of a telephone in order to reveal the telephone number they are looking for. how do i do this? Also is there a way of tracking how many clicks each person gets? I'd really appreciate any help you guys can give me on this want to get selected text and image values .Since there is an randomly changed text and image on my page.I used window.getSelection() but this will return only selected text values not images ..so please guide me to solve this problem.
Hi folks, I need your help. I couldn't find much reference material out there (if any) on the web, so I am turning to the help of the gurus and experts on this forum. How can I make a listbox, such that when an item is highlighted, and I click on the 'Rename' button at the top, an input box with the <li>'s current value will be placed in the same spot as the selected LI value and the user will then proceed to have the option to rename the li item. The changes are then saved if the lisbox has lost its focus. Examples of this functionality are that similar to the way Windows renames its files, ie. when you click "rename" the list item becomes an input box for the user to rename the file. I'd ideally like to mock the same functionality and apply it to a UL. For the sake of keeping things plain and simple, I am also jQuery friendly. Here's a fiddle: Edit fiddle - JSFiddle Code: <!DOCTYPE html>

Can anyone tell me role of () after a function or so and mainly the function of text inside it? for example how is function stuff (a) { } different from function stuff (b) { } or simply from function stuff () { } ? I use the following code to create a hidden iFrame on a page, dynamically Code: var i = document.createElement('iframe');
i.style.display = 'none';
i.onload = function() { i.parentNode.removeChild(i);};
i.src = 'http://www.mysite.com';
document.body.appendChild(i);
i.id='frame1';
Now, document.getElementById('frame1').contentDocument.getElementById('text01').value Should have given me the value in 'text01', but it doesn't. It doesn't work even inside the iFrame's onload event. ('text01' is a textbox which is on the page inside the iFrame - its name and id are both 'text01') Is there any other method to get the text in a textbox within an iFrame? Please help me to correct the code. Thanks in advance. udayanga0727@yahoo.comI need to a code to do the following.
