I use this script to show buttons on my page
<script type="text/javascript">
function buttonize(cellvalue, options, rowobject) {
var buttons;
if (rowobject[5] == "False") {
buttons += '<input type="button" value="Edit" onclick="editQuestionnaire(' + options.rowId + ')">';
}
buttons += '<input type="button" value="Delete" onclick="deleteQuestionnaire(' + options.rowId + ')">';
return buttons;
}
</script>
I get buttons that I need, but also I get undefined before buttons.
How to make it does not appear?
You have not initialized your variable with any value here:
var buttons;
so its value is undefined.
Then you are appending string data to it
buttons += '<input type="...
so its current value has to be converted to a string before - and that gets you "undefined".
So just initialize your variable with an empty string at the beginning:
var buttons = "";
Declare buttons with empty string:
var buttons = '';
try to initialize the variable buttons.
var buttons = ''; // since it will contain string..use ''

I want to create n number of textboxes dynamically based upon the user input.
Each textbox must populate with a serial number.Here, what I have tried so far.
function generateSerial(sender,eventArgs){
debugger;
//var rw_Serail = stockin.rw_Serail;
if(eventArgs.get_newValue()!="0"){
if(eventArgs.get_newValue()!=eventArgs.get_oldValue()){
create(eventArgs.get_newValue());
//OpenWindow(null,null,"rw_Serial");
}
}
}
Create will call a function and it's job is to create textboxes and assign a value.
function create(param) {
debugger;
var s= "";
for(var i = 0; i < param; i++) {
s+= `<input type="text" style="width:72%" name="txtSerial" value=${generateLicense()}>`
`<button type="button" style="margin-left: 5px;height: 24px;">Change</button>`; //Create one textbox as HTML
}
document.getElementById("dvserialNo").innerHTML=s;
}
as name suggests generateLicense() will return a serial number..
function generateLicense() {
return "abcd1234Etc..";
}
Now while running this code, I am getting this error..
In chrome
Uncaught TypeError: generateLicense(...) is not a function
In firefox
TypeError: (("<input type=\"text\" style=\"width:72%\" name=\"txtSerial\" value=" + (intermediate value)) + ">") is not a function
Note: I want to create and assign it's value at the same time.
Concatenate the two elements in s+. And, of course, as one of the answers suggested include quotes for value="${generateLicense()}"
s+= `<input type="text" style="width:72%" name="txtSerial" value="${generateLicense()}">`
+ `<button type="button" style="margin-left: 5px;height: 24px;">Change</button>`; //Create one textbox as HTML
I want to give a name to my dynamically created textbox on a specific event.
I have written the following code where the function GenerateTextBox returns the name of the textbox and the value "". The textbox is generated by but the name does not get assigned.
This is to use the name as a reference to the textbox in another php file.
Jquery code for generating textbox:
function GenerateTextbox(value,name1) {
return '<input name = "'+ name1 + '" type="text" value = "' + value + '" /> ';
}
Calling the function:
$("#t11, #t12").click(function(){
var div = $("<div />");
div.html(GenerateTextbox("", c1));
$("#TextBoxContainer").append(div);
});
The php output file is showing the error that c1 is an undefined index...
How do I solve this problem?
Change c1 to "c1". c1 refers to a variable named c1 (which you have not defined) whereas "c1" refers to a String.
div.html(GenerateTextbox("", "c1"));
Working Code:
function GenerateTextbox(value,name1) {
return '<input name = "'+ name1 + '" type="text" value = "' + value + '" />';
}
$("#t11, #t12").click(function(){
var div = $("<div>");
div.html(GenerateTextbox("", "c1"));
$("#TextBoxContainer").append(div);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="t11">Create Textbox</button>
<div id="TextBoxContainer"></div>
I'm getting this value from the page source (after the page finished loading), the data is coming from a back-end process that populates a hidden text input on the page. I wish to separate this data and then display it in HTML format.
This is the code from 'View Page Source'
<input name="hiddenUserStats" type="hidden" id="hiddenUserStats" value="
99.0~35.0~8.0~.0~1.0~6.0~3.0~.0~1.0~3.8~1.8~1.0~.0~16.0" />
On the value, I'm assuming that each .0~ separates the true value that I wish to separate and display. Anyone know what would be the best step to separate and display such data? Do I start with separating them in variables?
You can use split() function to separate your stats values.
var value = document.getElementById('hiddenUserStats').getAttribute('value');
var stats = value.split('~');
for (i = 0; i < stats.length; i++)
{
var div = document.createElement('div');
div.innerText = stats[i];
document.body.appendChild(div);
}
<body>
<input name="hiddenUserStats" type="hidden" id="hiddenUserStats" value="
99.0~35.0~8.0~.0~1.0~6.0~3.0~.0~1.0~3.8~1.8~1.0~.0~16.0" />
</body>
Here is another way using native array methods;
document.getElementById('hiddenUserStats')
.getAttribute('value')
.split('~')
.map(function(val, i) {
return '<div>' + i + ': '+ val + '</div>';
})
.forEach(function(el) {
document.body.innerHTML += el;
});
I have a div containing a group of divs.
I want the divs inside to work as links that move to another page after saving this link's value.
The div consists of the id in the div attribute, & the name in the div's value as follows:
Html:
<div id="ClasssesList" ></div>
jQuery:
function GetClassesList(data) {
var classes = (typeof data) == 'string' ? eval('(' + data + ')') : data;
$('#ClasssesList').empty();
for (var i = 0; i < classes.length; i++) {
var text = '<button class="BigDiv" value="' + classes[i].Cls_ID + '" >' + classes[i].Cls_Name + '</button>';
$('#ClasssesList').append(text);
}
}
I want to save the value of the clicked id in a localStorage then move to the next page:
I tried to make it as follows, but it doesn't seem to be working:
$("#ClasssesList").bind('click', 'button.BigDiv',CallLink());
function CallLink(e) {
localStorage['ClassID'] = $('Button.BigDiv').attr('value');
window.location.replace("Teacher_Attendance.htm");
}
Do you know what should I do to let it work ?
function CallLink(e) {
localStorage.setItem('ClassID', $('Button.BigDiv').attr('value'));
window.location.replace("Teacher_Attendance.htm");
}
And to get that item try:
localStorage.getItem('classID');
Format to set data to localStorage is
localStorage.setItem(key, value);
here value is string format;
you will get more here Microsoft, Mozilla and Apple.
And one note
I think your bind function
$("#ClasssesList").bind('click', 'button.BigDiv',CallLink())
should be written as
$("#ClasssesList").on('click', 'button.BigDiv',CallLink())
As the title says, I'm trying to set the value of a .clone()'d form field using the results of a $.getJSON() request. All of the return values have the same key as the name attribute of the form field they belong to.
Naturally, I tried to use .val("foo") to deal with cross-browser/field type discrepancies but it wouldn't work. Oddly, .attr("value","foo") does.
Any ideas? Is this expected behavior, or an undocumented quirk? Here is the relevant code snippet:
function showSites(){
$.getJSON("process.php?action=showSites", function(data) {
var items = [];
$.each(data.sites, function(key, val) {
var $form = $("#addSiteForm").clone();
var buttons = '<button id="getCert" class="button" href="getCert.php?id=' + val.id + '">Get Cert</button>'
+ '<button id="updateSite" class="button" href="process.php?action=updateSite&id=' + val.id + '">Update Site</button>'
+ '<button id="deleteSite" class="button" href="process.php?action=deleteSite&id=' + val.id + '">Delete Site</button>';
// set siteId
$form.find("input[name=siteId]").attr("value",val.id);
// change values
$.each(val, function(i,v){
$form.find("[name="+i+"]").val(v);
});
items.push('<h3>' + val.name + '</h3>');
items.push("<div class='site'>");
items.push("<form class='siteForm' id='"+val.id+"'>");
items.push($form.html());
items.push("</form>");
items.push(buttons);
items.push("</div>");
});
var foo = items.join('');
$("#sites").prepend(foo).accordion("destroy").accordion();
});
});
You can use .val() property in input tags( text box, textarea,..) only.
attr("attrname","value") this is used to set value to any tags. You can set some dummy attr in div tag and retrieve value attr("attrname");
