Javascript 到 return content/string 不适合给定的 UIWebView 宽度和高度

Javascript to return content/string which doesn't fit in given width and height of UIWebView

假设我的 div,

中有一些字符串

"This is a dummy text inside my html.This is just a test".

然后我会将它加载到 UIWebView,其中我的 webview width=100,height=20.Now 假设只有 "This is a dummy text inside" 适合 webview。

现在我想要我的 javascript 到 return 我剩下的字符串 "my html.This is just a test"(因为高度太小不适合) .

这里我不想调整我的 webview 的大小,我只想要不适合我的 UIWebView 的剩余字符串。

如有任何建议,我们将不胜感激...

                                     ***I'm newbiew to javascript...

使用 Below JS 函数..它将 return 溢出文本..

示例:

load_content('foo','Sample Text',30,100);


<script type="text/javascript">
    function load_content(div_tag_id,content_string,height,width){

        var text_fit = "";
        var text_overflow = "";
        var string_array = content_string.split(" ");

        for(var i = 0; i < string_array.length; i++ ) {

            document.getElementById(div_tag_id).style.width = width+"px";
            document.getElementById(div_tag_id).innerHTML = document.getElementById(div_tag_id).innerHTML + " "+string_array[i];
            if(document.getElementById(div_tag_id).offsetHeight > height) {
                text_overflow += " "+string_array[i];
            } else {
                text_fit += " "+string_array[i];
            }
        }
        document.getElementById(div_tag_id).innerHTML = text_fit;
        return text_overflow;

    }   
</script>
