<div><p></p></div>
I found when put in ,
$('div')[0].childNodes
it split the text node of into 2 text nodes,
#=>[textnode,<p></p>,textnode]
if I want write the text 'this is text node 3' into the last child node,
something like:
('div')[0].childNodes[2].value = 'this is text node 3'
but value property doesn't work here.how can I do this?
Instead of using .value try this the following, and give us feedback if it works.
$('div')[0].childNodes[2].innerHTML = 'this is text node 3';

Accept a customer number and then output the details of each order and items to an editor widget.
Display them in the editor widget ( editor-1 as object name).
define temp-table ttcustomer
field custnum like customer.cust-num
field cname like customer.name
field orders like order.order-num
field items like item.item-num
field itemname like item.item-name .
find first customer WHERE customer.cust-num = input f1 NO-LOCK .
create ttcustomer .
assign
ttcustomer.custnum = customer.cust-num
ttcustomer.cname = customer.name.
for each order WHERE Order.cust-num = input f1 NO-LOCK .
assign
ttcustomer.orders = order.order-num.
for each order-line where order-line.order-num = order.order-num no-lock.
for each item where item.item-num = order-line.item-num no-lock.
assign
ttcustomer.items = item.item-num
ttcustomer.itemname = item.item-name.
end.
end.
end.
I have no idea why you would want to display that on an editor. So I'll assume you want to concatenate the info you gathered in the for each loop into an editor.
So after the last end, you could do this:
define variable editor-1 as character view-as editor.
for each ttcustomer:
assign editor-1 = editor-1 + ttcustomer.items + ' ' + ttcustomer.itemname + chr(13).
end.
display editor-1.
If chr(13) doesn't work to skip a line, try chr(10).
PS: An editor is really probably not the widget you want to display this. I'd use a browse. But since the question asks for an editor, there.
PS2: You didn't assign the other fields you put on the temp-table, so I'm not displaying them. But it's just a matter of adding them to the assign line above, not forgetting the spaces, dashes or whatever you'd like to use as a separator.
I am trying to use PowerShell to pro-grammatically update notes in PowerPoint slide notes. Being able to do this will save tremendous amounts of time. The code below allows me to edit the notes field with PowerShell but it messes up the format each time.
$PowerpointFile = "C:\Users\username\Documents\test.pptx"
$Powerpoint = New-Object -ComObject powerpoint.application
$ppt = $Powerpoint.presentations.open($PowerpointFile, 2, $True, $False)
foreach($slide in $ppt.slides){
if($slide.NotesPage.Shapes[2].TextFrame.TextRange.Text -match "string"){
$slide.NotesPage.Shapes[2].TextFrame.TextRange.Text = $slide.NotesPage.Shapes[2].TextFrame.TextRange.Text -replace "string","stringreplaced"
}
}
Sleep -Seconds 3
$ppt.Save()
$Powerpoint.Quit()
For example, right now it will iterate through each slide's notes and update the word string to stringreplaced but then the entire notes text becomes bold. In my notes I have a single word at the top of the notes that is bold and then text below it. For example, a note on a slide my look like this:
Note Title
Help me with this string.
After PowerShell updates the notes field it saves it to a new .pptx file but the note now looks like this:
Note Title
Help me with this stringreplaced.
Any ideas on how to update slide notes without messing up any formatting found in the notes? It only messes up formatting for slides the script updates.
When you change the entire text content of a textrange in PPT, as your code's doing, the changed textrange will pick up the formatting of the first character in the range. I'm not sure how you'd do this in PowerShell, but here's an example in PPT VBA that demonstrates the same problem and shows how to use PPT's own Replace method instead to solve the problem:
Sub ExampleTextReplace()
' Assumes two shapes with text on Slide 1 of the current presentation
' Each has the text "This is some sample text"
' The first character of each is bolded
' Demonstrates the difference between different methods of replacing text
' within a string
Dim oSh As Shape
' First shape: change the text
Set oSh = ActivePresentation.Slides(1).Shapes(1)
With oSh.TextFrame.TextRange
.Text = Replace(.Text, "sample text", "example text")
End With
' Result: the entire text string is bolded
' Second shape: Use PowerPoint's Replace method instead
Set oSh = ActivePresentation.Slides(1).Shapes(2)
With oSh.TextFrame.TextRange
.Replace "sample text", "example text"
End With
' Result: only the first character of the text is bolded
' as it was originally
End Sub
I am trying to mask user's input in a datagridview column and i found this ready class Masked edit column Class that adds a 'mask edit column' option in the column types list. When i select this column type a mask field is being added in the list of column properties. I tried to do my job by adding some mask elements in this 'Mask' field, but when I run the code it didnt restrict me from adding other characters. I re-opened the 'edit columns menu' and I saw that the 'Mask' field was empty.
I want the text cell to accept 20 chars maximum and only: 1.Capital Letters(English & Greek), 2.these three chars(.,-), 3.Numbers 0-9
So as a first test i used only this mask(>????????????????????) but it didnt work as it didnt convert my characters to Uppercase and accepted more than 20 chars when i end the cell edit.
i am not sure the way to go is the Masked Text Box way. i have made many projects on vb and i used to use a loop in the textChanged event of a text box to restrict characters entry. the loop is this : (but i cant use it now in the valueChanged event cause it seems that 'value' doesn't have a selectionStart property.)
Dim charactersDisallowed As String = "!##$%^&*()+=|}{][:;?/><.,~""
Dim theText As String = txtCopies.Text
Dim Letter As String
Dim SelectionIndex As Integer = txtCopies.SelectionStart
Dim Change As Integer
For x As Integer = 0 To txtCopies.Text.Length - 1
Letter = txtCopies.Text.Substring(x, 1)
If charactersDisallowed.Contains(Letter) Then
theText = theText.Replace(Letter, String.Empty)
Change = 1
End If
Next
txtCopies.Text = theText
txtCopies.Select(SelectionIndex - Change, 0)
So,
Is a masked text cell what i need? and if yes( Why is this mask box not keeping the mask i enter? And how can i use this class to do my job?)
What can i alternately do to restrict some characters in a column's cells? (I will then convert to Uppercase on cellEndEdit)
I finally did it by removing the unwanted characters on cellvaluechanged event, which seems that is being raised when I end the cell's edit by for example hitting "Enter".
I often use this way to add a string to the last line in multiline editText.
Example: The before editText: (handles.txtLine)
line 1
line 2
line 3
and i want to add string "line 4" to it. So i do:
msg = get(handles.txtLine,'string');
msg_i = sprintf('\nline 4');
msg = [msg msg_i];
set(handles.txtLine,'string',msg)
Result:
line 1
line 2
line 3
line 4
Are there other methods to do the same function?
The String property of a multiline edit control can be set in three ways:
a multiline character array, e.g. txt1= ['line 1'; 'line 2']. Here txt1 has size 2x6.
a single line character array containing newline characters, e.g. txt2= sprintf('line 1\nline 2'). Here txt2 has size 1x13.
a cell array of strings, e.g. txt3 = {'line 1', 'line 2'}
You would add or remove text from the string in each case in different ways, and each method has advantages and disadvantages.
1 is usually inconvenient, as all your lines have to have exactly the same length, or be padded with spaces. But if that's the case, then it's easy to add or remove lines.
2 (basically the way you're doing it now) is also usually less convenient, as while it's easy to append lines, it's less easy to remove them from the middle unless you parse the string looking for newlines. But if you only ever need to add lines, it's probably fine.
I would modify the way you're using sprintf and then concatenating:
msg = sprintf('%s\n%s', msg, 'line 4');
is a simpler and more flexible syntax.
Your general method of getting, modifying and setting the String property is fine, although if you wanted you could combine it all into one starement, such as:
set(handles.txtLine, 'String', sprintf('%s\n%s', get(handles.txtLine, 'String'), 'line4'))
3 would typically be the most convenient, as long as you're comfortable with cell arrays. Each line can be whatever you like, and it's easy to add or remove items.
I have a form with a table in it. In each row is a table cell with a hidden input item with the name of it starting with "hf_id_" followed by a number so that row 1's field has a name of "hf_id_1", row 2 is "hf_id_2" and so on. I need to search all of these fields for a particular value but I'm not quite sure how to get to the hidden fields. I know how to get to them when the full name is known but in this case I'm not sure if there's a way to get an array of these where name starts with "hf_id_". Thanks.
You can search elements with ^ (starting with) and $ (ending with), example:
$('input[name^="hf_id_"]');
So you can get all those elements like:
var elements = $('input[name^="hf_id_"]');
And you can iterate over them to search for a particular value like:
$('input[name^="hf_id_"]').each(function(){
if ($(this).val() === 'search value here')
{
// found..........
}
});
Or you could simply use
$('input[type="hidden"]');
