Question

是否可以将UIWebView中的第一个字母大写？ UIWebview上没有autocapitalizationType属性，例如UITextField和UITextView（例如：textfield.autocapitalizationType = .sentences）

我在html文件中尝试过

<div id="editor-container" autocapitalize="on" style="padding:0px;margin-top:0px;font-family:'GothamPro-Light';font-size: 15px;"></div>

请尝试一下。它使用JavaScript在autocapitalize和words之间切换none。我需要在每个input事件中对div进行模糊（）和聚焦（）调整，否则键盘将无法拾取autocapitalize设置中的更改。

<html>
<head>
<script>
function getEditor() {
    return document.getElementById("editor")
}

function tickle(editor) {
    // This gets the keyboard to pick up the change in the autocapitalize setting.
    // Save the selection.
    selection = document.getSelection()
    anchorNode = selection.anchorNode
    anchorOffset = selection.anchorOffset
    editor.blur()
    editor.focus()
    // Restore the selection.
    document.getSelection().setBaseAndExtent(anchorNode, anchorOffset, anchorNode, anchorOffset)
}

function textChanged() {
    editor = getEditor()
    text = editor.textContent
    if (text.length != 0) {
        editor.autocapitalize = "none"
        tickle(editor)
    } else {
        editor.autocapitalize = "sentences"
        tickle(editor)
    }
}
</script>
</head>
<body onLoad="getEditor().addEventListener('input', textChanged)"><div id="editor" contentEditable="true" autocapitalize="sentences"></div></body>
</html>
