Javascript: Replace backslashes with double backslashes
提问by vm370
I'm currently having the problem mentioned in the title and I'm somehow not finding a way to properly replace backsashes with double backslashes, so that I can properly give the string to a webservice as parameters. Let me show you what I tried. Some of these do actually work for some other people, but not for me... I'm currently testing this with FF18.0.1
我目前遇到了标题中提到的问题，但不知何故我找不到用双反斜杠正确替换反斜杠的方法，以便我可以正确地将字符串作为参数提供给 web 服务。让我告诉你我的尝试。其中一些确实适用于其他一些人，但不适用于我......我目前正在使用 FF18.0.1 进行测试
WSParameters.replace(/\/g, "\\\\");
WSParameters.replace("\", "\\\\");
WSParameters.replace(/\/g, "\\");
WSParameters.replace(/\/g, "\\");
WSParameters.replace(/\/g, "\");
WSParameters.replace("\", "\\");
Thanks a lot in advance
非常感谢提前
EDIT: I should mention that it's somehow parsed into JSON and with firebug I see the backslash in the source string, but not in the JSON view. Maybe there is another way? But somehow it's already failing at the replacement of the backslashes.
编辑：我应该提到它以某种方式被解析为 JSON，并且使用 firebug 我在源字符串中看到反斜杠，但在 JSON 视图中没有。也许还有另一种方式？但不知何故，它已经在替换反斜杠方面失败了。
EDIT2:
编辑2：
if (noAction == false) {
$.ajax({
type: "POST",
url: "WebService.asmx/" + webMethod,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: pAsync,
data: WSParameters,
success: function callFunction(result) { processPOSTResults(result, pType, pNot);},
error: function (xhr, ajaxOptions, thrownError) {
alert('Error while communicating with WebAdmin web service. - ' + xhr.status + " " + thrownError);
}
});
}

WSParameters.replace(/\\/g, "\\\\");should do it, and in FF18 as well. Notice that if you use JSON.stringify, this is done automatically. Also watch out that many console outputs (Firebug etc) do surround string contents with quotes, but do not escape them.
WSParameters.replace(/\\/g, "\\\\");应该这样做，在FF18中也是如此。请注意，如果您使用JSON.stringify，这是自动完成的。还要注意许多控制台输出（Firebug 等）确实用引号将字符串内容括起来，但不要对它们进行转义。
