JavaScript - Passing Parameters From Html To Javascript
I am trying to pass a value using a parameter in html (asp) to a javascript function. When I try to pass a value inside of a variable <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1(tst);"> it simply doesn't work (no error msg - just nothing) while if I put a value in the call <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1('5393');"> it works fine. The javascript looks like this:
function OnButton1(tst) { var pth = "youth_edit3.asp?cIndex=" + tst; document.YouthEdit.action = pth; document.YouthEdit.submit(); // Submit the page } I've set tst = "5393" but it won't work when I try to pass it. Only a literal value of '5393' works. What am I doing wrong? Thank you in advance. Similar TutorialsHi, This is a noob question which I've searched all over for but can't find an answer..........which means it probably isn't possible Can I pass a parameter to a javascript function from embedded javascript? I have a function in a separate .js file which accepts a parameter as follows: function initialize(menu){ alert(menu); } When I use the following javascript embedded in my HTML it doesn't work: <SCRIPT LANGUAGE="javascript"> <!-- window.onload = initialize('testMenu'); // --> </SCRIPT> Am I doing something wrong or is this not possible? Thanks for your help Dear all, I'm passing the variables myTitle and myLink to form.php using javascript. This is the way I'm doing it: Code: <a href='form.php?title=" + myTitle +"&link="+myLink+">Click me</a> It's working great but sometimes myTitle and myLink contain the plus character (+). When this happens it's not passed. In the case of the title, it's just a problem of looks but in the case of the link, well, the link won't work without the character. As an example if the title is: Laptop + Accessories What is passed is: Laptop Accessories What can I do to pass also the plus character?? Thanks a lot!! Code: function viewDetails(rowid,linkid){ alert("enterining into bundles"); if(linkid=='seobundles') { alert("enetering into if "); document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeobundleW?rowindex="+rowid; document.chwAnnouncementW.submit(); } else { alert(linkid); document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeoW?rowindex="+rowid; document.chwAnnouncementW.submit(); } } Actually i am passing linkid="seobundles" as string but its not interpreting and it is always going to else part and not if part. I tried to print link id its teling its of object HTML table type and we are passing the two parameters rowid, linkid from a macro. rowid is working fine as and when we select radio buttion but linkid is not working as an string. IF i pur linkid in single quotes then also its not working I am passing parameters from one page (actually from a frame within a frameset) to another using Javascript. Typically the code is as follows, taking values from a Form. Code: parent.titleFrame.location="frm_right_demo_title.html?MyDateEvent.value='"+ytt+ "'&MyParam_spec.value='"+parent.mainFrame.document.forms.myForm.MyParam_spec.value+"'"; This has worked fine in all browsers including IE, Chrome and Firefox version 2.0.0.2. However, I have now found that it doesn't work with Firefox version 3.6.12. This is because when retrieving the parameters in the new loaded page, the character ' (quote) has been converted to %27 (percent twenty seven). I can write code to replace %27 with the quote character. However, this is lengthy and time-consuming (as I need to have cyclic code as the javascript replace command seems to work only on the first occurrence within a string). Can someone please help me to understand why this is happening and how to overcome it? I have added an event listener to a LI item in the DOM: liNode.addEventListener("mouseover", mouseOn, true); The mouseOn function: function mouseOn(e) { // Test for IE or Firefox var e = (!e)?window.event:e; var yPos; if (e.pageY) { yPos = e.pageY; } else { yPos = e.clientY; } } I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this? I have two versions of this document. The first version uses only JavaScript and the standard PROMPT(). It works very well, but I would like to insert the name prompt into the page using the input command. For some reason the variable loaded in the HTML statement doesn't get passed to the JavaScript. Any ideas would be appreciated! This is only a small test page.

I have a list of buttons, each with a different id which is taken from the ids of these values from the database. When I click one of the buttons it shows the items that correspond to this id in the database. Therefore, when different buttons are clicked the display changes to match the objects relating to this particular button. When a button is clicked, this shows various other objects which I can then select (using a checkbox). When a checkbox is clicked, a Javascript function is called to change the html text next to the appropriate button. However, I can't get this to work as I need to pass the id of the button, and the html span, to the Javascript in order to change the correct text. Here is my Javascript : Code: function questionnum(checkbox) { if(checkbox.checked) { var qdesNumElement = document.getElementById('<?php echo $q;?>'); var qdesNum = qdesNumElement.innerHTML; qdesNumElement.innerHTML = ++qdesNum; } This code only gets the last button. Please help. i, Am developing a webform using PL/SQL. Am using javascript to do some form validation Sample if(a =="") { alert("Please enter the first name"); return false; } else if(b =="") { alert("Please enter the last name"); return false; } else if (y !="Test1") { if (y != "Test2") { if (y != "Test3") { alert("Enter the right text"); return false; } } alert("am wrong outside"); } else if(z =="") { alert("Please fill al the fields"); return false; } it passes till alter("am wrong outside") and executes the procedure but doesnt goes to the last else part. I want it to go the last else part too. Please help. I'm more of an actionscript person but got roped into an html/javascript job. What I need to do, and it shouldn't be that difficult is this: page1.html - there is a yellow button and a red button - if the user clicks on the yellow button I want to set a cookie with the value "yel" then load the next page - if they click the red button set that cookie with the value "red" page2.html - 'onload' i want to read that cookie and load up the main image to match, something like this maybe?... document.mainimage.src='img/main_' + variable + '.png' so that the path would be for example 'img/main_red.png' Any help please? Preferably javascript only and as simple as possible. If you think this would be easier sending that variable in the URL instead of as a cookie please explain. I'm having a very hard time searching for tutorials that are any good and that do exactly this kind of thing. |
