JavaScript - Changing Attributes Of An Existing Window
I'm not really much of a javascript programmer, but I occasionally use javascript that I've found here and there. But I'm unable to find anything that helps me in what I'm trying to do now.
I regularly use a snippet of code that pops up a small window to display an image or a very small html file. Using the window.open() function, I'm able to disable scrolling, resizing, etc., and size it to my needs. I'll have a window.close link somewhere on the page. But in my current project, my customer's page has several links related to other companies. When you click on the link, an that company's ad pops up in a small window. At this point, the viewer can simply close the window, or they should be able to click on the ad and be taken to that company's website. I'm able to have it close the window and open that new url in the parent browser window, but my website customer doesn't want their site to go away. They want the new company's website in a new window. Or I can simply NOT close the popup window, but now the new company's website is in a relatively small browser window, unable to scroll, resize, etc. Is there a way for me to somehow modify an existing window with an onclick directive - something similar to the window.open() function, OR open a new browser window with window.open() AND close the popup window? If I haven't made myself clear, let me know and I'll try to explain myself better. Thanks in advance for any help. Similar TutorialsHi everyone, I'm currently in the process of making a spreadsheet like webpage and it all working fine... However I have been using setAttribute and removeAttribute in order to dynamically change a table cells onclick property. This of course does not work in IE7 etc and I've been banging my head against a brick wall trying to come up with a solution that will work in all browsers but I just can't seem to get it to work with using methods such as... Code: document.getElementById(myElementId).onclick = scriptToRun;
document.getElementById(myElementId).attachEvent('onclick',scriptToRun);
I get all sorts of not implemented, type mismatch errors when I try to use the above. Below is the setAttribute code which works. Code: document.getElementById("task_" + colName + studentId).setAttribute("onclick","showTaskDropDown('task_" + colName + studentId + "','" + studentId + "','" + colName + "','" + value + "','" + maxValue + "','" + trafficMaxValue + "','" + taskNumber + "')");
If anyone can see why the other methods aren't working and can provide a solution I'll be extremely greatful! Hi All I have a piece of script which makes a div slide out from the side of the screen with information on it. I can change the innerHtml etc no problem, but i have a problem with change .style attributes dynamically. My code: Code: var mystring = "height:500px";
var keyVal = mystring.split(":")
var slidingDiv = document.getElementById('slidingDiv');
slidingDiv.style.keyVal[0] = keyVal[1];
As you see above i get a value which i need to split() to get the key and value to use. So what i would like to see is: Quote: slidingDiv.style.height = 500px; But it does not work, as there is no such function as slidingDiv.style.keyVal[0]; How do i change this? I hope I've explained this thoroughly enough. Please ask if i need to explain further. Regards Marinus I have written base rel="nofollow" target="_self" tag in head tag. It works fine in IE6 but not in IE8. window.showModalDialog() opens up new ModalDialog instead of using existing Dialog. Can anybody help me?
Ok, 'nother head-banger for the hardcore! I have a "contact us" <a> with the id 'contact' on the main page, which is supposed to change the source file of an iframe to the contact page. Except when I click on "contact us" nothing happens. I've tried to get this to work several different ways, and suspect that the problem is purely syntax, but I just haven't been able to figure it out. Here's the code: The snippet on the main page (index.html): Code:
<div id="linkListContact" class="LinkList">
<img id="linkListContactBg" class="SideBarBgImg" src="Assets/Backgrounds/SideBar/ContactBg.png"></img>
<span>
<ul>
<li>
<div><a id="contact">Contact Us</a>
</div>
</li>
</ul>
</span>
</div>
... and the relevant Javascript: Code:
function setIFrame(frameSource)
{
document.getElementById('mainWindow').src = frameSource;
}
function setContactLink()
{
var contactURL = "http://katabasis.spreadshirt.com/shop/imprint"
document.getElementById('contact').onclick = new Function ( "setIFrame( 'contactURL' )" );
}
The setIFrame function is used to call the content initially when the page loads, and is working beautifully in that context. You can see the problem in action at the actual site: www.katabasis-apparel.com. Thanks. Hey there. I want to move a div around a page, and I do this by getting the original top and left values of a div, and then change them. But the problem is getting the original values; I checked online and thought that this would work: Code: var chart = document.getElementById(charDiv).style.top;
var charl = document.getElementById(charDiv).style.left;
alert('char_t:' + chart + ' char_l:' + charl + 'charDiv:' + charDiv);
charDiv is passed into the function (its the id of the div I want to move). I know that charDiv has a value by looking at the values of the alert() statement, but the values of chart and charl are empty. The alert simply outputs char_t: char_l: charDiv: charOne any help would be appreciated Hi Guys, I'm new at JS. I need to remove TR elements from parent table but the problem is there are no table ID/Name Is it possible to perform it? Please see attach - i need remove red marked block... what scrip i have to use if i will put it to the green block? Thank you. how about getting the attributes of the a tag? href and title and the innerhtml (actually the innerhtml has space on both ends)
hello Sir/Mam i have a piece of code here that creates a dynamic form.. Code: <script type='text/javascript' language='javascript'>
<!--
function createTextbox(){
var textboxtag = document.createElement("input");
textboxtag.setAttribute("name","username");
document.getElementById("form1").appendChild(textboxtag);
}
-->
</script>
<body>
<div id='div1'>
<button name='textbox' onclick='createTextbox()'>Textbox</button>
</div>
<div id='div2'>
<form id='form1' action='#' method='post'>
</form>
</div>
</body>
this code sets the "name" attribute to "username" automatically.. my problem is how to set the name attribute manually by the user after the dynamic textbox is created.. just like in visual basic where after you create a form e.g button or textfield, theres a side pane where you can change attributes like name, value, etc.. tnx for the time reading my post..sorry for my poor explanation of the problem..im new in javascript and trying to learn it all by myself.. I attempting to set attributes for all tags of a particular type.... I have a bunch of thumbnails <img> tags; when I wand over them I would like to show the corresponding large image with a script but the tags require onMouseOver events. I really don't feel like adding a bunch of onMouseOver="myShowScript" attributes to every img tag manually... my scripts aren't working... partly because I'm a newbie... I'm sure there is some fundamental concept about java and html I don't get... here's ONE of the versions that doesn't work.. I've tried a few things but I'm open to scrapping everything for a better way... I appreciate any direction you can offer... Code: function addAtts(){
var numberOf = document.getElementsByTagName("img");
for(i = 0; i < numberOf.length; i++){
numberOf[i].onMouseOver="myShowScript()";
}
}
I am looking to get a loop which runs through a series of divs (each with an attribute called "position" followed by 5 comma separated values). for each of these divs i need the 5 comma separated values (from position) to be assigned to variables. I have the rest of the code sorted out i just cannot get the original variables. Examples: divs look like this... Code: <div position="100,100,50,50,1"></div> There are no limits on the number of these divs but there will never be 0. What i want is something to look like this. For each div, var s = string of attribute (position) values (output:a,b,c,d,e) split string to create var a = a var b = b var c = c var d = d var e = e I from those 5 vars can do what i need. and i know that vars a,b,c,d,e,s will all be overwritten in when it comes to the next div... that is planned. Which is considered best practice? Code: <div onmouseover="doThis();">
myDiv.onmouseover = doThis;
myDiv.addEventListener("mouseover",doThis,false);
...or something else? how to search through siblings for shared attributes I have a a long list of links and I suppose Im going to apply a number of classes to each one [describing a number of attributes for each] and I want to do a conditional search probably in javascript/jquery so that when i hover over one of the links I highlight its relatives - those that have the same attributes. What Im having trouble wrapping my head around is the idea of classes to ID these custom attributes. The attributes are coming from a database converted to XML. In my Javascript I essentially want to say that for each link should the user mouseover or mouseclick for each of its sibling links if its sibling link share its attributes style or highlight these compliant siblings a certain way how do I do the 'if statement' without spelling out every possible attribute entry? I know in plain OOP Java how I could test for this but in that scenario I have access to these entries as fields in an object's instantiation. Help? thanks so much in advance Hi, I'm not even sure if that's the issue here, but I've isolated it and all the other code is working, so what I'm thinking is that if this: Code: function togglePoly(poly_num) {
if (document.getElementById('poly'+poly_num)) {
if (document.getElementById('poly'+poly_num).checked) {
gpolys[poly_num].show();
} else {
gpolys[poly_num].hide();
}
}
}
function createClickablePolyline(poly, html, label) {
gpolys.push(poly);
var poly_num = gpolys.length - 1;
if (!html) {html = "";}
else { html += "<br>";}
if (html) {
GEvent.addListener(poly,'click', function(point) {
if (!point) point = poly.getVertex(Math.floor(poly.getVertexCount()/2));
map.openInfoWindowHtml(point,html);
});
}
label = "<a href='javascript:GEvent.trigger(gpolys["+poly_num+"],\"click\");'>"+label+"</a>";
// add a line to the sidebar html
sidebar_html += '<input type="checkbox" id="poly'+poly_num+'" checked="checked" onclick="togglePoly('+poly_num+');">' + label + '<br />';
}
document.getElementById("sidebar").innerHTML = sidebar_html;
works here to hide/show a line, then this: Code: function show(category) {
for (var a=0; a<gpolylines.length; a++) {
if (gpolylines[a].mycategory == category) {
gpolylines[a].show();
}
}
for (var i=0; i<pts.length; i++) {
if (pts[i].mycategory == category) {
pts[i].show();
}
}
}
function hide(category) {
for (var a=0; a<gpolylines.length; a++) {
if (gpolylines[a].mycategory == category) {
gpolylines[a].hide();
}
}
for (var i=0; i<pts.length; i++) {
if (pts[i].mycategory == category) {
pts[i].hide();
}
}
}
// this variable will collect the html which will eventually be placed in the sidebar
function togglePoly(category) {
if (document.getElementById(category)) {
if (document.getElementById(category).checked) {
show(category);
} else {
hide(category);
}
}
}
function createClickablePolyline(poly, html, name,category) {
gpolys.push(poly);
var poly_num = gpolys.length - 1;
var category = lines[a].getAttribute("category");
midLineArrows(pts, category);
GEvent.addListener(poly,'click', function(point) {
if (!point) point = poly.getVertex(Math.floor(poly.getVertexCount()/2));
map.openInfoWindowHtml(point,html);
});
// add a line to the sidebar html
label = "<a href='javascript:GEvent.trigger(gpolys["+poly_num+"],\"click\");'>"+label+"</a>";
sidebar_html += '<input type="checkbox" id="'+category+'" checked="checked" onclick="togglePoly('+category+');">' + label + '<br />';
}
document.getElementById("sidebar").innerHTML = sidebar_html;
should work here to show/hide lines and arrows the difference of course being that the first code uses poly_num, which is taken directly from the Code: var poly_num = gpolys.length - 1; code (because it only needs to show/hide one line at a time) whereas the second uses the xml attribute "category" from here Code: var category = lines[a].getAttribute("category");
because it's attempting to hide and show a line with arrows on it (the arrows being in the pts array), both of which share the category attribute. It's not throwing up any major errors, but it's not working, either... any suggestions would be great... thanks in advance... Hi, I'm having trouble with some flash players that don't abide by the style attribute of the div they're created in using Javascript. When the flash-players' source is hard-coded into the page source they render fine, but the more players, the more bloat as you can see in the source of the original page. Any help?

Here is the program: http://www.1728.com/newwindow.htm Basically, I want to input a number in the input box, which assigns a number to the variable numval located at document.box1.b1. When clicking on the "new window" button, an alert displays the input box value, then another window opens and displays the integers 1 through 12 and the amount squared. I would like the new window to obtain the number from the previous window so that the new window will display integers (and their squares) from 1 to the value of numval. hello everybody i need your help and experience for having code to show ( overlay / modal window ) to the user when closing or navigating away from the page ( i want put in this window facebook share to make the user to share the page in his facebook ) , bytheway i wanna use it in my wordpress in every post could it be happen ? Thanks for helping I am looking to have a link open a closeable window that is contained within a browser window. If you click on the "sizing charts" link on this website, this is exactly what I am looking to do: http://www.bella.com/mapper.php?pageid=40 The window is contained within the current browser window, it can be dragged around, but not outside the parameters of the browser window. Is there a title for this technique that I can research? Not looking to waste anybodys time, but if I can get steered in the right direction it would be greatly appreciated. Thanks I have created and opened a child window called "checkwin" and have written some data to it. If the data is valid, I want the user to click on the 'CONFIRM' button on the child window, at which time I want the "submit()" function for the form on the parent window to be executed. If the data is invalid the user clicks on 'MODIFY' and I want focus to return to a field on the parent form. However, when I click on the "CONFIRM" or "MODIFY" buttons on the child window, nothing happens. Here is the code: Code: checkwin.document.write("</td></tr><tr><td align='right'><input type='button' value='CONFIRM'
onclick='opener.document.personnel_form.submit()'></td><td></td><td><input type='button' value='MODIFY'
onclick='opener.document.personnel_form.first_name.focus()'></td></tr></table>")
