I need to remove target=_blank from all hyper links so that all links will be opened in the same webview. 我需要从所有超级链接中删除target=_blank ，以便所有链接都将在同一Web视图中打开。 When i searched for similar Q&As most of them suggested injecting a javascript which would convert all target=_blanks to _self . 当我搜索类似的Q＆A时，他们中的大多数建议注入一个javascript，它将所有target=_blanks转换为_self 。 I am testing this in a browser window first, and the script indeed converts all hyperlinks but it has no effect, it still continues to open in a new window. 我首先在浏览器窗口中对此进行了测试，该脚本确实转换了所有超链接，但没有任何效果，它仍然继续在新窗口中打开。 How can I force it to open in same window/webview ? 如何强制在同一窗口/ WebView中打开它？

var a = document.getElementsByTagName("a");
for (i=0; i<a.length; i++)
    if (a[i].target == "_blank")
        a[i].target = "_self";

Actually, your JavaScript is correct. 实际上，您的JavaScript是正确的。 I suspect you've created test html page to check it. 我怀疑您已经创建了测试html页面进行检查。 In this case, you need to place script in the end of page, otherwise it will not affect links: 在这种情况下，您需要将脚本放在页面末尾，否则不会影响链接：

<body>
<!-- This will work -->
<a target="_blank" href="https://google.com">google.com</a>
<script>
    var a = document.getElementsByTagName("a");
    for (i=0; i<a.length; i++)
        if (a[i].target == "_blank")
            a[i].target = "_self";
</script>
<!-- This link will not be modified -->
<a target="_blank" href="https://google.com">google.com</a>
</body>

You need to inject this script in your WebView . 您需要将此脚本注入WebView 。 Use following code in your WebFrameLoadDelegate : 在您的WebFrameLoadDelegate使用以下代码：

- (void)webView:(WebView *)sender didFinishLoadForFrame:(WebFrame *)frame {
    NSString *script = @"var a = document.getElementsByTagName(\"a\");\n" \
                        "for (i=0; i<a.length; i++) {\n" \
                        "    if (a[i].target == \"_blank\") {\n" \
                        "        a[i].target = \"_self\";\n" \
                        "    }\n" \
                        "};";
    [frame.javaScriptContext evaluateScript:script];
}

Note that this script should be performed for each frame separately. 请注意，应针对每个帧分别执行此脚本。

Hope it helps. 希望能帮助到你。
