What should file paths fed to insertCSS() be relative to?

问题

I'm starting out with phonegap and have found the docs to be a bit vauge on this point.

When I use insertCSS() on my current project it seems like whatever path I use, the css is not used.

As you can see from that link, my file structure is:

app-root
|
...
|_ www
    |
    |_ css
    |   |
    |   target.css
    |
    |_ js
    |   |
    |   index.js
    |   
    index.html

In index.js I'm making a call to insertCSS() in the event listener for an inAppBrowser.

This function should be pulling target.css:

iab.addEventListener('loadstop', function() {
    // Once loaded, add css
    iab.insertCSS( { file: "target.css" } );
});

But... it doesn't

I've tried multiple different relative file paths like css/target.css and ../css/target.css but they don't seem to work.

What am I missing?

回答1:

Internal type styling in CSS generally have a higher order of precedence over external styling.

Therefore This (from your GitHub Code):

iab.insertCSS( { code: "body { background-color: green; }" }, function(){
  iab.insertCSS( { code: "body { background-color: green; }" } );

would always be executed instead of this:

iab.insertCSS( { file: "../css/chat.window.css" }

since they are both styling the same element. The complete order of precedence from top priority to least is:

1. Inline Style (top priority)
2. Internal Style
3. External Style (least priority)
