JavaScript - Dynamically Showing Field Based On Text Value From Another Field
I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box. I would like to use onBlur but can't seem to get it to work.
Can I do this? Help Similar TutorialsI am having trouble writing this javascript for my work, normally I would do this in ASP or PHP, but the environment I am working with will only allow javascript for dynamic function. The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. Here are the mappings: If selections = Elementary & Vocabulary = http://www.widget.com/content/elem-vocab If selections = Elementary & Writing = http://www.widget.com/content/elem-writing If selections = Elementary & ELD = http://www.widget.com/content/elem-eld If selections = Middle School & Vocabulary = http://www.widget.com/content/midscl-vocab If selections = Middle School & Writing = http://www.widget.com/content/midscl-writing If selections = Middle School & ELD = http://www.widget.com/content/midscl-eld If selections = High School & Vocabulary = http://www.widget.com/content/hiscl-vocab If selections = High School & Writing = http://www.widget.com/content/hiscl-writing If selections = High School & ELD = http://www.widget.com/content/hiscl-eld Here's a snippet of a different method that I tried, but it did not work. I think the above mentioned method would probably be best. Code: <script language="javascript" type="text/javascript">
<!--
function build() {
document.fillgaps.redirect.value = "http://www.widget.com/content/" + document.fillgaps.grade.value + "-" + document.fillgaps.solution.value ;
//print example: http://www.widget.com/content/ELM-VOC
return true;
}
-->
</script>
<form name="fillgaps" action="http://www.widget.com/submit.aspx" method="post" onSubmit="return build();">
<input type="hidden" name="redirect" value="">

Hi all, Thanks for reading. I'm having an issue trying to accomplish the following - I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly? Code: <script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
fields = 2;
} else if (fields = 2) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;
} else {
document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;
}
}
</script>
Here is the code in my HTML - Code: <input type="text" name="field1" size="25" /> <span>Field 1.</span> <div id="addedMore"></div> <p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p> Thank you very much. Hi, I'm hoping this will be an easy one for you experts out there. I am working on a convention registration form. What I'm trying to do is have the text "50.00" pop into the COST field when any text (even if it's only one character) is entered into the NAME field. If the text in the NAME field is deleted, the "50.00" should also be deleted. Does anyone have a script that does this? Thanks! I have two drop down fields. When I select any value in the first drop down i want the second dropdown to automatically populate the value related to the first one. For e.g i have the first field as name and the second field as measured in. If I select 'Potato' in the first dropdown then the second drop down should populate 'kg'. Please help.
Hi Experts, I have designed an online registration system for a non profit in ASP/SQL. After the members register for classes they are automatically redirected to an invoice page with class fees. At the bottom of the page I have a Total Fees field of all the classes. The member is supposed to pay this amount to our organization. Question: We decided to do an online payment this year and would like to calculate a 2% additional amount on the Total Fees. This amount is paid to the Payment Merchant site. We cannot afford to lose the 2% since we are a non profit. Would really appreciate if someone can tell me how to 1) Add a new field under the Total field 2) And calculate the 2% additional fees and do a Grand Total. Thanks in advance. I have a form that has a pretty complicated combo box - a user starts typing text, it queries a database for matches, and displays the results to the user. The user can then select the match they desire and it has a value id, which I am currently sending to a hidden field in the form. So, for example: user starts typing in a movie name, Seven - it returns Seven and user selects it. The form submits the id of the movie seven (say 12) to a hidden field. Where I am stumped: Once a user selects a movie title, I have another drop down select box that is to display the available formats of the movie by querying my database based on the product id (12) and returning the available formats in the list: DVD BLUERAY VHS I am pretty good at programming, but I cannot figure this out - how to make the select box fire and return results once the value for the textbox has been captured. Can anyone help me? Hi, I am trying to write some code that will test if a user enters a non-numeric character in an input text field, and if so, replaces it with a '0' Code:
<script type="text/javascript">
function IsNumVal (){
for (J=1; J<=3; J++){
if (isNaN(Number(document.getElementById('Intext' + J).value))){
document.getElementById('Intext' + J).value = 0;
}
}
}
</script>
<Body>
<table border="1" cellspacing="1" id = "Numbers">
<tr id="RowNum1">
<td ><input type="text" size = "5" name="Intext1" id="Intext1" value = "3"
onkeyup="IsNumVal()" /></td>
</tr>
<tr id="RowNum2">
<td><input type="text" size = "5" name="Intext2" id="Intext2" value = "9"
onkeyup="IsNumVal()" /></td>
</tr>
<tr id="RowNum3">
<td><input type="text" size = "5" name="Intext3" id="Intext3" value = "18"
onkeyup="IsNumVal()" /></td>
</tr>
</table>
</Body>
document.getElementById('Intext' + J).value = 0; doesn't work document.Schedule.'Intext' + J.value = 0; doesn't work document.Schedule.Intext2.value = 0; works, but I need to test each text field while looping, so I can't "hard code" the ID. Suggestions? I am very very new to programming and trying to create a web interface for a model. The user needs to be able to add as many compounds as they want and add a variable number of subgroups for each compound. Also, each input needs a distinct name. I have tried adapting someone else code to add/remove form inputs but am not having any luck creating subgroups. below is my code Code: <html>

any help would be appreciated. thanks I am trying to calculate age based on the date of birth input into a text field. the date field should allow users to enter a one or two digit month, one or two digit date and a two or four digit year. Users should be able to enter any of the following date formats: 11-2-10, 1-25-2010, or 01/25/2010. On some days it works and others it wont, like 11-1-91 returns that the user is under 18. Code: function checkAge(){
var stDate = document.getElementById("birth").value;
var dayPartToDate = parseInt(stDate.substring(0,2),10);
var monPartToDate = parseInt(stDate.substring(3,5),10);
var yearPartToDate = parseInt(stDate.substring(6,10),10);
var dtTo = new Date(yearPartToDate, monPartToDate-1, dayPartToDate);
var mydate = new Date();
mydate.setDate(mydate.getDate());
var bday = dtTo - mydate
if (bday < 18){
window.alert("You must be 18 to rent equipment.");
document.getElementById("birth").value = "";
}
}
Here is what I'm envisioning: The user selects a state, then in the 'Cities' box, he starts typing the name of his city. However, it autocompletes the name for him based on the state he chose. So if he chose California and started typing in "Los Angeles", it would autocomplete "Los Angeles" for him. Does that make sense? Is there a script out there that can do this? hiiii, im new to javascripts . Can anyone help me to know that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry.... plz share knowledge u will be more knowledgeable Hi All, I have a form that captures member registration details. In the admin section .. I would like to change the Status field of a record/s from NEW to PAYMENT DUE after 14 days from the data of submission. The status change should automatically trigger on the 15th day. So when the admin checks the list page he/she should be able to view the updated status field. Any pointers how to accomplish this? Thanks in advance. Vinny Hi, Is there anyone who could help me figure out how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work. Any help would be greatly appreciated, thanks. <script language="JavaScript"> function changelist() { //here we assign the value of the hidden input to x x=eval(document.getElementByName("SelectLists[40]"); if(document.getElementById("SelectLists[40]").selected=true x=SelectLists[40] else(document.getElementById("SelectLists[41]").selected=true x=SelectLists[41] else(document.getElementById("SelectLists[42]").selected=true x=SelectLists[42] //now we assign the new value to the input document.getElementById("theHiddenInput").name=x; //and now we test alert(document.getElementById("theHiddenInput").name) } </script> <input type="hidden" id="theHiddenInput" name="SelectLists[40]" value="Yes"> <select class="inpBox" style="width: 287px" name='mailinglist' id="lists" onchange="changelist()"> <option value="SelectLists[40]" name="SelectLists[40]" id="SelectLists[40]">MyList</option> <option value="SelectLists[41]" name="SelectLists[41]" id="SelectLists[41]">testlist</option> <option value="SelectLists[42]" name="SelectLists[42]" id="SelectLists[42]">testlist2</option> Hi Guys, i am wondering if there is a way to have an auto Complete form field from a db table data ? thanks Hi folks. Looking to see if anyone could tell me where I'm going wrong with this script... I'm trying to have a field automatically filled with the day of the week ("Monday", "Tuesday", "Wednesday" and so on), upon the user selecting a date from the datepicker jQuery. If this isn't clear, I'll clarify further down the page. Here is the script: Code: <script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[428]"]').change(function(){
var d = $('input[name="item_meta[428]"]').val();
var n = new Date(d).getDay();
if(n == 0)
val v = 'Sunday';
else if(n == 1)
val v = 'Monday';
else if(n == 2)
val v = 'Tuesday';
else if(n == 3)
val v = 'Wednesday';
else if(n == 4)
val v = 'Thursday';
else if(n == 5)
val v = 'Friday';
else if(n == 6)
val v = 'Saturday';
$('input[name="item_meta[429]"]').val(v).change();
});
});
</script>
I'm basically trying to say, if the user selected today (15/05/2012) in the field 428 it would fill the field 429 with "Tuesday". Again, if the user selected 18/05/2012 in the field 428 then it would automatically fill field 429 with "Friday". It's being done to work in conjunction with a wordpress plugin called Formidable Pro hence the item_meta[428] etc. Any assistance would be greatly appreciated. Sam. Hi Guys, Im in need of some help with regards to forms. I am looking to build as basic as possible, a form that has 3 select dropdowns that have predetermined options. The user will select the first option and based on that option the second will populate and based on that, the third one will give the last option. Now, when the last one is selected, i need a div or a paragraph displaying information to be displayed. So here's the framework. Option 1 = fruit or vegitables of which fruit is selected is selected by the user Option 2 = Apples, Grapes, and pears of which apples is then selected Option 3 = Red, Green and Yellow of which Green is selected. Once green is selected, I need a description about the green aple to be displayed. Can anyone help me out on this? I am not sure where to begin and my boss is adament it must be done like yesterday. Ay help will be appreciated. Thanks. For various reasons, I need the value of my drop down box options to contain size information rather than price. However I would like to be able to calculate a price for the items based on what size the user selects as well as the quantity. Below is the code I came up with (which doesn't work obviously) What can I do to get this to work for me? Thanks in advance for any help! Code: <head>
<script type="text/javascript">
<!--
function calc(A,B,SUM) {
var price = document.getElementById(A).extrainfo;
var quantity = document.getElementById(B).value;
document.getElementById(SUM).value = price * quantity;
}
//-->
</script>
</head>
<body>
<label>T-Shirt:
<select name="T_SHIRT" id="T_SHIRT" onchange="calc('T_SHIRT','Tshirt_QTY','total');">
<option selected="selected">CHOOSE A SIZE </option>
<option value="SIZE: SMALL" extrainfo="10.99">Small, 34/36 (S) </option>
<option value="SIZE: MEDIUM" extrainfo="11.99">Medium, 38/40 (M) </option>
<option value="SIZE LARGE" extrainfo="12.99">Large, 42/44 (L) </option>
</select>
</label>
<label>QTY:
<input type="text" id="Tshirt_QTY" name="Tshirt_QTY" onchange="calc('T_SHIRT','Tshirt_QTY','total')" />
</label>
<label>Price:
<input type="text" readonly="readonly" name="total" id="total"/>
</label>
</body>
I type something on the current textarea/input and all the values get removed after I add another field. Is there a solution? Code: <script language="Javascript" type="text/javascript">
<!--
//Add more fields dynamically.
function addField(area,field,limit) {
if(!document.getElementById) return; //Prevent older browsers from getting any further.
var field_area = document.getElementById(area);
var all_inputs = field_area.getElementsByTagName("input"); //Get all the input fields in the given area.
//Find the count of the last element of the list. It will be in the format '<field><number>'. If the
// field given in the argument is 'friend_' the last id will be 'friend_4'.
var last_item = all_inputs.length - 1;
var last = all_inputs[last_item].id;
var count = Number(last.split("_")[1]) + 1;
//If the maximum number of elements have been reached, exit the function.
// If the given limit is lower than 0, infinite number of fields can be created.
if(count > limit && limit > 0) return;
//Older Method
field_area.innerHTML += "<li><textarea id='steps' name='steps[]' rows='5' cols='40'></textarea><br /><input id='steps_image' name='steps_image[]' /></li>";
}
//-->
</script>
<ol id="steps_area"><li>

</li>
</ol>
<input type="button" value="Add" onclick="addField('steps_area','',15);"/>
Ok, here is my issue. I want to have an input text on the top of the page that when I type in a series of numbers and hit submit, it populates the rest of the form. Does anyone have any idea what I need to perform this action?
