JavaScript - Disable Button When Selecting Dropdown Item
hi again
hi i want to create a form Form have 2 submit buttons also have one drop down list when selecting dropdown list item disable the one submit button plzzzzzz help m for do this with sample code needed. Similar TutorialsGreetings experts, this is my first time here. So, please take easy on me. I have makup with 2 sections. The first section contains 5 form fields and are required. The second second has 2 form fields and are optional. Users can only choose from one section or the other but not both. The js script below ensures that if users select from section 2, section one will not challenge for validation and works a treat. The challenge I have now is to ensure that if users choose from section 1, the 2 form fields in section are automatically disabled so they won't be attempted to choose from it. Similarly, if users select from section 2, all form fields in section one are automatically disabled so they won't be tempted to choose from that section. Is this possible? If not possible, is it possible to raise an error? For instance, a user selects from section 1 and attempts to select from any of the 2 form fields in section 2, a message that says, "You can only select from one section but from both. Similarly if a user selects from section 2 first, same thing happens. Thanks very much for your assistance. function validate() { if(document.getElementById("<%=txtrequest.ClientID%>").value != "" && document.getElementById("<%=txtreceived.ClientID %>").value != "") { if (document.getElementById("<%=txtName.ClientID%>").value == "") { alert("Please enter name"); document.getElementById("<%=txtName.ClientID%>").focus(); return false; } if (document.getElementById("<%=txtCity.ClientID %>").value == "") { alert("Please enter city"); document.getElementById("<%=txtCity.ClientID %>").focus(); return false; } if (document.getElementById("<%=txtState.ClientID%>").value == "") { alert("Please enter state"); document.getElementById("<%=txtState.ClientID%>").focus(); return false; } if (document.getElementById("<%=txtZip.ClientID%>").value == "") { alert("Please enter zip"); document.getElementById("<%=txtZip.ClientID%>").focus(); return false; } if (checkradio() == false) { alert("Please enter contacts"); document.getElementById("<%=txtContacts.ClientID%>").focus(); return false; } } return true; } hey guys The first dropdown has some options as : abc(a) bcd(a) cde(b) def(b) efg(c) fgh(c) The second dropdown has : a b c On selecting abc(a) in first dropdown the 'a' must get selected in second dropdown,on selecting cde(b) second dropdown must have 'b' and so on,also the second dropdown value should be disabled(grayed out) for user.Need the code in javascript.ty in advance. I currently have two html select list boxes side by side on a form, two buttons in between the boxes to move items from list box to the other, and a javascript function to control the movement of the items from one box to the other. Here is the javascript: Code:
function MoveSelected(from, to) {
var lstFrom = $(from);
var lstTo = $(to);
for (var i = 0; i<lstFrom.length;i++) {
if ( lstFrom[i].selected ) {
var elOptNew = document.createElement('option');
elOptNew.text = lstFrom[i].text;
elOptNew.value = lstFrom[i].value;
try {
lstTo.add(elOptNew, null); // standards compliant; doesn't work in IE
} catch(ex) {
lstTo.add(elOptNew); // IE only
}
}
}
for (var i = lstFrom.length-1; i>=0;i--) {
if ( lstFrom[i].selected ) {
lstFrom.options[i] = null;
}
}
}
Here are the two html form select list boxes (lstAvailProd is the starting list box that lists the initial data and lstSelectProd is the destination list box): Code:
<td width="10%" valign="center">
<a href="javascript: MoveSelected('lstAvailProd','lstSelectProd');"><IMG SRC="buttons/right_arrow.gif" style="padding-bottom: 2px;" /></a><br /><br />
<a href="javascript: MoveSelected('lstSelectProd','lstAvailProd');"><IMG SRC="buttons/left_arrow.gif" /></a>
</td>
I was wondering if anyone could tell me how I could modify my code to allow for the selection of all the data in the starting list box by only selecting and moving the first item in the list to the destination list box? The first item is called "All Products", so instead of actually selecting every product in the starting list and moving them to the destination list, I would like the code to see that if the "All Products" list item is moved to the destination list, move all the other list items in the destination list back to the starting list. Here's an example of what the code for each list box looks like: Starting List Box: Code:
<select name="lstAvailProd" id="lstAvailProd" multiple="true" size="8" style="width: 250px;">
<option value="-1">{All Products}</option>
<option value="1">Product 1</option>
<option value="2">Product 2</option>
<option value="3">Product 3</option>
<option value="4">Product 4</option>
<option value="5">Product 5</option>
</select>
Destination List Box: Code: <select name="lstSelectProd" id="lstSelectProd" multiple="true" size="8" style="width: 250px;"> </select> Any help would be appreciated, thanks!! I have up to 3 dropdown lists that I can select using javascript functions. Depending on what I select in the first dropdown loads what is in the 2nd drop down and so on. i want to be able to select the first drop down and it skips the 2nd one and displays the 3rd one. How do I do that with the current functions I am using. Code: function cboSourceChange(){
var iSource = document.frmHarvestForm.cboSource.options[document.frmHarvestForm.cboSource.selectedIndex].value;
var iSub1 = document.frmHarvestForm.cboSub1.options[document.frmHarvestForm.cboSub1.selectedIndex].value;
var iSub2 = document.frmHarvestForm.cboSub2.options[document.frmHarvestForm.cboSub2.selectedIndex].value;
var dtBeginDate = document.frmHarvestForm.txtBeginDate.value;
var dtEndDate = document.frmHarvestForm.txtEndDate.value;
var iIndCert = document.frmHarvestForm.cboIndCert.value;
location.replace("HarvestBoard.asp?cboSource="+iSource+"&cboSub1=0&cboSub2=0&cboSub3=0&txtBeginDate="+dtBeginDate+"&txtEndDate="+dtEndDate+"&cboIndCert="+iIndCert);
}
function cboSub1Change(){
var iSource = document.frmHarvestForm.cboSource.options[document.frmHarvestForm.cboSource.selectedIndex].value;
var iSub1 = document.frmHarvestForm.cboSub1.options[document.frmHarvestForm.cboSub1.selectedIndex].value;
var dtBeginDate = document.frmHarvestForm.txtBeginDate.value;
var dtEndDate = document.frmHarvestForm.txtEndDate.value;
var iIndCert = document.frmHarvestForm.cboIndCert.value;
location.replace("HarvestBoard.asp?cboSource="+iSource+"&cboSub1="+iSub1+"&cboSub2=0&cboSub3=0&txtBeginDate="+dtBeginDate+"&txtEndDate="+dtEndDate+"&cboIndCert="+iIndCert);
}
function cboSub2Change(){
var iSource = document.frmHarvestForm.cboSource.options[document.frmHarvestForm.cboSource.selectedIndex].value;
var iSub1 = document.frmHarvestForm.cboSub1.options[document.frmHarvestForm.cboSub1.selectedIndex].value;
var iSub2 = document.frmHarvestForm.cboSub2.options[document.frmHarvestForm.cboSub2.selectedIndex].value;
var dtBeginDate = document.frmHarvestForm.txtBeginDate.value;
var dtEndDate = document.frmHarvestForm.txtEndDate.value;
var iIndCert = document.frmHarvestForm.cboIndCert.value;
location.replace("HarvestBoard.asp?cboSource="+iSource+"&cboSub1="+iSub1+"&cboSub2="+iSub2+"&cboSub3=0&txtBeginDate="+dtBeginDate+"&txtEndDate="+dtEndDate+"&cboIndCert="+iIndCert);
}
function cboSub3Change(){
var iSource = document.frmHarvestForm.cboSource.options[document.frmHarvestForm.cboSource.selectedIndex].value;
var iSub1 = document.frmHarvestForm.cboSub1.options[document.frmHarvestForm.cboSub1.selectedIndex].value;

Hi, I have two dropdown lists with the second one being dependent on the selection in the first. Options in list 1: 1,3 or 4 List two should be enabled when 3 or 4 is selected in list 1. So far so good, managed to get it to work with only one set of lists, but I actually have 18 of those sets in this form: Code: <select name="fw[$i]" id="fw[$i]"> <option value="1">FWH</option> <option value="3">links</option> <option value="4">rechts</option> <option value="0" selected></option> </select><br /> <select name="lie[$i]" id="lie[$i]" disabled="disabled" onchange="showBox($i,xxx);"> <option value="0" selected>---</option> <option value="1">gut</option> <option value="2">schlecht</option> <option value="3">Strafschlag</option> <option value="4">OB</option> </select> $i is my index generated by my PHP script and runs from 1 to 18. Everything works just fine as long as the index is not in play. With the index my function breaks, most probably due to my inability to extract the second parameter (xxx above) from the selection field. Here's my function, there could be something wrong there too with how exactly to specify the proper dropdown list to enable. Code: function showBox(field,val) {
if (val > 1) {
var box = 'lie[' + field + ']';
document.form1.box.disabled == false;
}
else {
document.form1.box.disabled == true;
}
}
Finally, I'm not that adept in javascript programming, more like a trial and error guy, how has hit the wall with this problem. Thanks in advance! Joe Ok so let's say I have this dropdown with a list of these items: PALCO TRIBUNA ORO And in a button on the page I want to send it one of those names, let's say I send it ORO, and through Javascript select that in the dropdown list. How is this done? Do I have to iterate through everything, and how? Thanks for any help in the subject. Have problem with IE8. Before IE 8, I can disable a drop-down box, but the selected item still there highlighted. But IE 8 makes the highlight go away. Is there any way to keep the original, Disable a item, you still keep the lightlights Thanksl
Below I have dynamical generated radio buttons, the names($approve variable is the name) per radio button pairs are different(dynamically created names using looping). When I create two buttons, one is for if you click it, all the radio button with the label approve will be selected all, and the other button is for the disapprove label button that will select the radio button with the label disapprove. How can I make this right. Below are the codes I created. Thanks Code: <script>
function selectAll()
{
var i = 0;
objElems = document.t4.elements;
for(i=0;i<objElems.length;i++){
objElems[i].checked =true;
}
</script>
PHP Code: <form action="viewall.php" method="post" name="t4"> while(condition) { echo "<td ><input type='radio' name='". $approve."' id='app' value='approve' /> Approve<br /> </td> <td ><input type='radio' name='". $approve."' id='disp' value='disapprove' /> Disapprove<br /> </td> "; } <tr><td><input type="button" name="all_app" value="Select All Approve" onclick="selectAll(this.value);" ></td> <td><input type="button" name="all_app2" value="Select All disapprove" onclick="selectAll(this.value);" ></td> </tr> </form> I am making a simple puzzle game on Android using Phonegap, that is HTML5, CSS3 and JavaScript. When a user fills an answer on a page, if the answer is correct, it will go to another page. However, once the user goes to the next page, he/she CANNOT return back to the previous page. I do not want the user to return back, else he/she will have to fill the answer again to go to the next page, so it's not good. Thank Hello Friends, i have a small problem and need your help.

Thanks in advance. Hi Experts .. not sure if this is the right forum. However here is my question: I have a date field with 25 values (prepopulated Radio Buttons) where we are asking the members to select one day to volunteer. Once a member selects a day we would like to disable that Radio button value (Greyed out) for other members. So basically out of 25 available days we would like to disable values as soon as a member selects one. The field is on a classic ASP form with SQL Server backend. How can I accomplish the above?
