How to call vue method from a javascript function?

I am trying to call a vue method from javascript function but can't make it work. The method I am trying to call is app.onChangePlant(val) It turns out that the value is not called.
Is it because of the vue is not yet available when I declared the javascript function?
This is the error I am receiving
plant-consumer:222 Uncaught TypeError: app.onChangePlant is not a function

I don't know why would you like to do that but if it's neccessary you can try to use window eventlisteners:
https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Creating_and_triggering_events
In your component you can add an eventlistener that call your method, in js script tage you can fire an event, if your component ready it will call the method.
I never did this before it's just a theory :)
edit: I tried it, but your component is not mounted when you want to fire the event in script tag

How to print multiple html2canvas

I have a form with mutiple steps. However, I would like to print them separately and save. The problem is that before the html2canvas completes rendering, the info has been saved. Therefore causing the image file to be empty. Below is my code.
html2canvas($('#content'), {
onrendered: function (canvas) {
var all = document.getElementsByClassName("tab");
html2canvas(document.getElementsByClassName("tab")[0], {
onrendered: function (canvas) {
Student.DocumentData = canvas.toDataURL().replace(/^data[:]image\/(png|jpg|jpeg)[;]base64,/i, "");
Student.DocumentName = 'Student Registration Form';
}
})
html2canvas(document.getElementsByClassName("tab")[1], {
onrendered: function (canvas) {
Student.DocumentData2 = canvas.toDataURL().replace(/^data[:]image\/(png|jpg|jpeg)[;]base64,/i, "");
Student.DocumentName2 = 'SPH Form';
}
})
html2canvas(document.getElementsByClassName("tab")[2], {
onrendered: function (canvas) {
Student.DocumentData3 = canvas.toDataURL().replace(/^data[:]image\/(png|jpg|jpeg)[;]base64,/i, "");
Student.DocumentName3 = 'Parent Consent Form';
}
})
}
var request = $.ajax({
url: "/API/Students/",
method: "POST",
cache: false,
data: Student,
dataType: "json",
error: function (jqXHR, status, error) {
alert(jqXHR.status + '. ' + jqXHR.statusText + '. ');
},
success: function (data, status, jqXHR) {
var msg = "";
for (index = 0; index < data.Message.length; ++index) {
msg += data.Message[index] + "\n";
}
alert(msg);
if (data.StudentID !== 0) {
$("input[id!='btnSubmit'],select,textarea").each(function () {
$(this).val('');
});
}
location.reload();
},
complete: function (jqXHR, status) {
$('#btnSubmit').prop('disabled', false);

This may be your infinite loop.
$.getJSON:call // async

You could try putting the $(document).ajaxStop(fn) binding inside of the $.getJSON callback

How to solve Uncaught TypeError: Cannot read property 'length' of null

says my function is undefined when assigning to a variable

i have a problem. I am trying to add a functions return value to a variable but it says the function is undefined. Here is my code. :
var selectedExpenseList = getSelectedExpenseIDs();
here is my function:
function getSelectedExpenseIDs() {
var selectedExpensesList = new Array;
var i = 0;
$('.expenseCheckBox:checked').each(function () {
if ($(this)[0].id !== "checkAllExpenses") {
selectedExpensesList[i] = $(this)[0].id.split('_')[1];
++i;
}
});
return selectedExpensesList;
}
EDIT: here is my entire function: I am trying to delete something from a list if a person has checked it.
var selectedExpenseList;
function actuallyDeleteTheExpense(canDeleteExpenses)
{
selectedTasksList = getSelectedTaskIDs();
var deleteTrackers = false, deleteExpenses = false;
if (canDeleteExpenses && !canDeleteTrackers)
{
$.Zebra_Dialog('Do you wish to remove Expenses?',
{
'type': 'question',
'title': 'Confirmation',
'buttons': [
{
caption: 'Yes', callback: function () {
deleteTrackers = false;
deleteExpenses = true;
doTheDelete(deleteExpenses);
}
},
{
caption: 'No',
callback: function () {
doTheDelete(deleteExpenses);
}
}
]
});
}
}
function doTheDelete(doIDeleteExpenses)
{
if (selectedTasksList.length > 0)
{
$.ajax({
type: "POST",
//url: "/Tasks/ViewTasks.aspx/deleteTasksAndLinkedItems",
url: '<%=ResolveUrl("~/Expenses/ViewExpenses.aspx/deleteSelectedExpense")%>',
data: "{ 'TaskIDs': [" + selectedTasksList.join(',') + "], DeleteTrackers : " + doIDeleteTrackers + ", DeleteExpenses : " + doIDeleteExpenses + " }",
//fix data
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
var ss = data.d;
if (ss.length > 0) {
for (var i = 0; i < ss.length; ++i) {
$.noty.consumeAlert({ layout: 'center', type: 'error', dismissQueue: true });
alert(ss[i]);
}
}
$("#viewTasksGrid").flexReload();
},
error: function (data) {
$.noty.consumeAlert({ layout: 'center', type: 'error', dismissQueue: true, modal: true });
alert('Error Deleting Tasks');
if (window.console) {
console.log(data);
}
}
});
} else {
showMessage('No tasks are selected.');
}
}
//end delete expense
function getSelectedExpenseIDs() {
var selectedExpensesList = new Array;
var i = 0;
$('.expenseCheckBox:checked').each(function () {
if ($(this)[0].id !== "checkAllExpenses") {
selectedExpensesList[i] = $(this)[0].id.split('_')[1];
++i;
}
});
return selectedExpensesList;
}

I noticed that your function code is tabbed once more than your code that calls it. It's possible that your function is scoped improperly (e.g. it's declared inside another function and you're calling it from outside that function).
If your function is coming back as undefined, it's almost certainly a scoping issue. I see nothing wrong with the function itself.
For instance:
$(document).ready(function () {
function myFunction() {
return 3;
}
});
var bob = myFunction(); //Error: myFunction is not defined.
