Menu
I am trying to load the following html as a string into a webview:
<html>
<head>
<script>
function foo() {
// test.
}
</script>
</head>
<body>
<p>hi.</p>
</body>
</html>
------------------------------
String content = readAboveContentIntoString();
WebView webview = ...;
webview.loadData(content, "text/html", "utf-8");
I get the following message from the webview console:
Uncaught SyntaxError: Unexpected end of input
If I remove the "// test." comment, I don't get the syntax error. It's as if the webview is stripping newlines, and so the function body is applying the comment to the closing brace like so:
function foo() { // test. }
Can anyone else repro this? I thought maybe my readAboveContentIntoString() was stripping newlines, but tested and it is not. I'm using android 4.4.4.
Thanks
-- Edit ---
Also, a block comment works fine in place of the line comment:
/* test. */

I had the same problem. It seems the only way is to remove comments from content string first and then load it to webview.
String content = readAboveContentIntoString();
WebView webview = ...;
// Add This :
content = removeComment(content);
webview.loadData(content, "text/html", "utf-8");
The function removeComment() removes both single line comments and block comments.
private String removeComment(String codeString){
int pointer;
int[] pos;
String str = codeString;
while(true) {
pointer = 0;
pos = new int[2];
pos[0] = str.indexOf("/*",pointer);
pos[1] = str.indexOf("//",pointer);
int xPos = xMin(pos);
if(xPos != -1){
//========================= Pos 0
if(xPos == pos[0]){
pointer = xPos + 2;
int pos2 = str.indexOf("*/", pointer);
if(pos2 != -1){
str = str.substring(0,xPos) + str.substring(pos2+2,str.length());
}
else{
str = str.substring(0,xPos);
break;
}
}
//========================= Pos 1
if(xPos == pos[1]){
pointer = xPos + 2;
int pos2 = str.indexOf('\n', pointer);
if(pos2 != -1){
str = str.substring(0,xPos) + str.substring(pos2+1,str.length());
}
else{
str = str.substring(0,xPos);
break;
}
}
}
else break;
}
return str;
}
private int xMin(int[] x){
int out = -1;
for(int i = 0;i < x.length;i++){
if(x[i] > out)out = x[i];
}
if(out == -1)return out;
for(int i = 0;i < x.length;i++){
if(x[i] != -1 && x[i] < out)out = x[i];
}
return out;
}
