[英]Injecting javascript with BHO using C# - how to escape strings properly
I have the following code in C# that I'm able to attach to IE, and it runs through fine until I hit the JSON, which I receive a javascript error complaining about the syntax. 我在C#中有以下代码,可以将其附加到IE,并且可以正常运行,直到遇到JSON(我收到一个抱怨语法的JavaScript错误)为止。 How exactly should I escape javscript code within C# ?
我到底应该如何在C#中转义javscript代码?
string jsonStr = @"[
{ \'name\': \'Obj1\', \'description\': \'Test description...\', \'url\':\'http://www.test.com\' },
{ \'name\': \'Obj2\', \'description\': \'Testing...\', \'url\':\'http://www.test.com\' },
{ \'name\': \'Obj3\', \'description\': \'Welp...\', \'url\':\'http://www.test.com\' }
]";
IHTMLScriptElement scriptObject = (IHTMLScriptElement)document.createElement("script");
scriptObject.type = @"text/javascript";
scriptObject.text = @"function test() {
var Edit = 'document.getElementById(\'tTest\').innerHTML = \'<h2 class=\'label3\'><span>Foo</span></h2><ol class=\'container-list\'>';
var json = '" + jsonStr + @"';
$.each(json, function (index, x) {
Edit += '<li class=\'test1\'><h3><a href=\'#\'><b>' + x.name + '</b> 1</a></h3><div class=\'url\'><cite>' + x.url + '</cite></div><div class=\'creative\'>' + x.description + '</div></li>';
});
Edit += '</ol>\';
eval('Edit');
}";
((HTMLHeadElement)head).appendChild((IHTMLDOMNode)scriptObject);
IHTMLDocument2 doc = (IHTMLDocument2)this._webBrowser2.Document;
IHTMLWindow2 parentWindow = doc.parentWindow;
if (parentWindow != null)
parentWindow.execScript("test();", "javascript");
The c# code is fine, I'm just having trouble wrapping my head about injecting the javascript code with all the quotations, single quotes, etc to eliminate the javascript error. C#代码很好,我只是想把所有的引号,单引号等注入javascript代码以消除javascript错误的麻烦。 Any help is GREATLY appreciated!
任何帮助是极大的赞赏!
When using verbatim string literals prefixed with @, it means that the enclosed string is treated as literal. 当使用以@开头的逐字字符串文字时,表示将封闭的字符串视为文字。 So basically no backslash '\\' escaping.
因此,基本上没有反斜杠“ \\”转义。 To escape double quote ("), just double it ("").
要转义双引号(“),只需将其双引号(”“)。
string jsonStr = @"[
{""name"": ""Obj1"", ""description"": ""Test description..."", ""url"":""http://www.test.com"" },
{ ""name"": ""Obj2"", ""description"": ""Testing..."", ""url"":""http://www.test.com"" },
{ ""name"": ""Obj3"", ""description"": ""Welp..."", ""url"":""http://www.test.com"" }
]";
