I am using jquery to gather data from a dynamically created table via Jquery. I am able to get the data, but now I want to sum up the fields and put the result inside a text field or label etc dynamically when I press enter. I am using the following code:
$("#iq").keypress(function(e)
{
if(e.which==13)
{
var tot=0;
$('#tab .itemtotal').each(function()
{
tot = tot + parseInt($(this).html());
});
$("#totalamount").val(tot);
}
});
My problem is that the value showing in the textfield is zero or NaN for the first time and after that its calculating correctly. I used the same code and associating it with a button and checking its click event and its working properly and showing first item also.
Any suggestions? If need some more clarification let me know. Thanks in advance.

So I created the following script to select all check boxes on a page
(function(d) {
var input = d.querySelectorAll('input[type="checkbox"]');
var i = input.length;
while (i--) {
input[i].checked = true;
}
})(this.document);
It does work to do that, however when trying it in Quickbooks while it does select all the boxes, the website does not register it as actually being selected (the total cost at the bottom remains the same, its like it superficially checks the boxes, visually only with no actual register). Any help would be great.
EDIT: Maybe simulating a click instead of changing the box values?
The only thing that changes when physically selecting a box is the value posted below changes to true from false
You should do :
input[i].setAttribute("checked", "");
The checked attribute is a boolean attribute, so the standard way to add it to an element is to pass an empty string for value.

I am trying to determine the selected item in a selector and submit a form based on the selection. Below is my Javascript.
$("#runjob").click(function() {
var selectedJob = document.getElementById('batchjob_selector').value.trim();
if(selectedJob == "Open Batch") {
alert(selectedJob);
document.getElementById('openbatchform').submit();
}
});
I checked in the console and the line document.getElementById('batchjob_selector').value.trim(); changes value based on selection, but for some reason it is always doing what's inside the if statement even when the selection has changed, the alert displays the correct selection. I am not sure what the problem is, any help is appreciated.
is batchjob_selector a select? because if that the case value will no contains what you are expecting, to get selected option from a select use following code
var selector = document.getElementById('batchjob_selector');
var selectedJob = selector.options[selector.selectedIndex];
I want to display tables when a selection is made in a form and a 'Generate Factsheet' button is clicked. I've got a working code where I individually hide other divs when displaying the one I am interested in. Since I have several options in the form (and hence several corresponding divs in which the respective tables are enclosed), the final code appears bulky. I want to write a function to hide other divs whiles displaying the one I am interested in. This is the code I currently have:
var tableDivs = ['tableOPVDiv','tablePneumoDiv','tableRotaDiv'];
var selectedVaccine;
var selectedTableDiv;
function generateFactsheetFunction(){
// Selecting the vaccine chosen from the dropdown
var e = document.getElementById("selectVaccine");
selectedVaccine = e.options[e.selectedIndex].text;
console.log("selectedVaccine: ", selectedVaccine);
if (selectedVaccine=="Rotavirus Vaccine"){
selectedTableDiv='tableRotaDiv';
console.log("rotavirus selected");
hideOtherTables();
} else if (selectedVaccine=="Polio Vaccine"){
console.log("polio selected");
selectedTableDiv='tableOPVDiv';
hideOtherTables();
} else if (selectedVaccine=="Pneumococcal Vaccine"){
console.log("pneumo selected");
selectedTableDiv='tablePneumoDiv';
hideOtherTables();
}
}
function hideOtherTables(){
var testa = tableDivs.indexOf(selectedTableDiv);
console.log("tableDivs[testa]: ", tableDivs[testa]);
console.log("testa: ", testa);
testb = tableDivs[testa];
console.log("testb: ", testb);
document.getElementById(tableDivs[testa]).style.display="block";
/*var newTableDivs=tableDivs.splice(testa);*/
/*for (y=0;y<newTableDivs.length;y++){
document.getElementById(newTableDivs[y]).style.display="none";
}*/
}
The uncommented part works fine. In the commented part, I want to say that for all array elements other than selectedVaccine, I want the display to be:
document.getElementById(tableDivs[testa]).style.display="none";
I cannot splice the data because the selections are repititive (the selections are from a form). What is the way to set the visibility of tableDivs associated with other selections to be none.
Why should you change the display property of each and every division seperately? give a common class name to all the divisions and hide them all at once and then display only the required table.
$(".yourClass").hide();
document.getElementById(tableDivs[testa]).style.display="block";
You will have to use the jQuery Library too.
If you are not familiar with jQuery then use the for loop to hide all the tables first and then display only the required table.
for (y=0;y<TableDivs.length;y++){//you need not create newTableDivs
document.getElementById(TableDivs[y]).style.display="none";
}
document.getElementById(tableDivs[testa]).style.display="block";
i.e you just have to interchange the order of execution. ;)
Cannot read property 'style' of null this means that document.getElementById(tableDivs[y]) return null and can not find this element
try to write
document.getElementById("ElementId")
i am using jquery autocomplete plugin.i defined autocomplete on a text input element.i defined many methods also on autocomplete.i can't share whole code.but giving brief idea about my scenario.here is small code snippet
j$(".quick-text-search").autocomplete({
source: function(request,response){},
search: function(){console.log('coming to search');},
});
i defined source and search method.when i type in .quick-text-search element everything is working fine and its showing list items also. but when any other element is generating search event then no list is showing.for example from element checkbox when checkbox value is changed .here is code snippet of that
$('input:checkbox').change(function(){
// j$(this).parent().addClass('active');
var catList = getSelectedValues('category-selected');
console.log("catlist");
console.log(catList);
j$(".quick-text-search").autocomplete("search", "");
});
i think it should call search method .so there should something in browser console.but there is no 'coming to search' in browser console. can anyone guideline why and how to generate search event in jquery for autocomplete??
No search will happen if the text length is less than the min options
If you go to the jQuery UI sample page: http://jqueryui.com/resources/demos/autocomplete/default.html
and you run the following into the console, nothing happens since the min length is 1.
$("#tags")
.autocomplete("search", "");
If you change it to search for "a", it will show the results
$("#tags")
.autocomplete("search", "a");
Now if we change the min length to zero and run the same code again the options open up
$("#tags")
.autocomplete("option","minLength", 0)
.autocomplete("search", "");
I'm trying to create form for printing with dynamically generated inputs.
Contents of the fields is shown later in PreviewDiv.
It works fine as long as I specify where they should be, for example:
$('#Prw_CapacityA_1').text($('#CapacityA_1').val());
$('#Prw_CapacityB_1').text($('#CapacityB_1').val());
$('#Prw_CapacityC_1').text($('#CapacityC_1').val());
But if the user creates 100 fields this would be a lot of code to write.
There must be other methods to fix this dynamically, for example:
$('#Prw_CapacityA_'+ counter).text($('#CapacityA_'+ counter).val());
Here's the js fiddle
You could try using attribute starts with selector to select the elements starting with the specific id's and then loop through them using the each() function.
There is no need to have html within your preview table. You can generate it when the user clicks on preview. Modified fiddle
$('#PreviewButton').click(function(){
var capB = $('td input[id^=CapacityB_]');
var capC = $('td input[id^=CapacityC_]');
var table = $("#AddFieldsToPreviewDiv");
table.empty(); //build table everytime user previews so that previously appended values are removed
table.append('<tr><td>ID</td><td>Text 1</td><td>Text 2</td><td>Text 3</td></tr>');
$('td input[id^=CapacityA_]').each(function(i){
table.append('<tr><td>#'+(i + 1)
+'</td><td>'+$(this).val()
+'</td><td>'+$(capB[i]).val()
+'</td><td>'+$(capC[i]).val()
+'</td></tr>');
});
// Show PreviewDiv and hide FormDiv if PreviewButton clicked
$('#PreviewDiv').show();
$('#FormDiv').hide();
});
You could try giving them a unique class (Normally I'd suggest ID but you're using one) say a class of "getinfo"
You could then try the .each() function
https://api.jquery.com/each/
$( ".getinfo" ).each(function( index ) {
var text = $(this).val();
alert(text);
});
This will make an alert box for every element it finds with the class 'getinfo' and then retrieve the value and display it, I hope this gives you a better idea.
If the amount of inputs can change from one page load to the next then you need to use a loop, rather than pulling all the values by 'hand', More code will help better understand what you're trying to achieve and from what.
