Android Question executeJavascript problem in webview

[cbanks]

Why does the first section of code work, but not the second (Code is in the page finished sub)? It works (moves down to named anchor) when I don't use a variable, it doesn't work when I use a variable.

Sub Activity_Create(FirstTime As Boolean)
    FlingableWebView1.LoadUrl("http://alumnihighschool.net/scriptures/bm/1_ne/1.html")
End Sub

Sub FlingableWebView1_PageFinished (url As String)
    Dim Javascript As String
    Javascript = "window.location.hash='#1: 8'"
    WebViewExtras1.executeJavascript(FlingableWebView1, Javascript)
End Sub

Sub Activity_Create(FirstTime As Boolean)
    FlingableWebView1.LoadUrl("http://alumnihighschool.net/scriptures/bm/1_ne/1.html")
End Sub

Sub FlingableWebView1_PageFinished (url As String)
    TagsAnchorName = "#1: 8"
    Dim Javascript As String
    Javascript = "window.location.hash='" & TagsAnchorName & "'"
    WebViewExtras1.executeJavascript(FlingableWebView1, Javascript)
End Sub

WebViewExtras1.executeJavascript(FlingableWebView1, Javascript)

I'm the only one that don't knows Javascript !
I try to guess: some characters need to be preceded by "\" (in your TagsAnchorName)

Any ideas on which ones and how?

 

[LucaMs]

I don't remember (my brain has few ram bytes )
but some chars, in some "environment", need that char, backslash.

You can try:

TagsAnchorName = "\#1: 8"

or

TagsAnchorName = "\#1\: 8"

It is known as "escape char", used for "special" chars

i would try it with
Javascript = "window.location.hash='#1: 8\'"

The ' is an special char which has to be escaped.

But i dont know wheter
#1: 8'
is an allowed anchor-name.

I would suggest to rename the anchorname to just chars and numbers (NOT beginning with a number)

->> #anchorname1

With such a name you would have less problems. btw: spaces are not allowed in anchors

Thanks for all your help! I got it working by only including the numbers as variables.
