我有一个表示元素的HTML字符串:“<li>text</li>”。我想将它附加到DOM中的一个元素(在我的例子中是一个ul)。如何使用Prototype或DOM方法做到这一点?

(我知道我可以在jQuery中轻松做到这一点,但不幸的是,我们没有使用jQuery。)

最新JS示例:

<template id="woof-sd-feature-box">
<div class="woof-sd-feature-box" data-key="__KEY__" data-title="__TITLE__" data-data="__OPTIONS__">
    <h4>__TITLE__</h4>
    <div class="woof-sd-form-item-anchor">
        <img src="img/move.png" alt="">
    </div>
</div>

</template>

<script>
create(example_object) {
        let html = document.getElementById('woof-sd-feature-box').innerHTML;
        html = html.replaceAll('__KEY__', example_object.dataset.key);
        html = html.replaceAll('__TITLE__', example_object.dataset.title);
        html = html.replaceAll('__OPTIONS__', example_object.dataset.data);
        //convertion HTML to DOM element and prepending it into another element
        const dom = (new DOMParser()).parseFromString(html, "text/html");
        this.container.prepend(dom.querySelector('.woof-sd-feature-box'));
    }
</script>

解决方案-适用于自IE 4.0以来的所有浏览器

var htmlString = `<body><header class="text-1">Hello World</header><div id="table"><!--TABLE HERE--></div></body>`;
var tableString = `<table class="table"><thead><tr><th>th cell</th></tr></thead><tbody><tr><td>td cell</td></tr></tbody></table>`;


var doc = document.implementation.createHTMLDocument();
    doc.open();
    doc.write(htmlString);
    doc.getElementById('table').insertAdjacentHTML('beforeend', tableString);
    doc.close();

console.log(doc);

或者你可以使用DOMParser

var doc = (new DOMParser).parseFromString(htmlString, "text/html");
    doc.getElementById('table').insertAdjacentHTML('beforeend', tableString);

console.log(doc);

以下是如何使用PrototypeJS(正如OP 12年前最初要求的那样):

HTML格式:

<ul id="mylist"></ul>

JS:

$('mylist').insert('<li>text</li>');

注意,这不是jQuery!

这是我的代码,它有效:

function parseTableHtml(s) { // s is string
    var div = document.createElement('table');
    div.innerHTML = s;

    var tr = div.getElementsByTagName('tr');
    // ...
}

参观https://www.codegrepper.com/code-examples/javascript/convert+a+字符串+to+html+元素+in+js

const stringToHtml = function (str) {
    var parser = new DOMParser();
    var doc = parser.parseFromString(str, 'text/html');
    return doc.body;
}

实际上,我想我会分享我想出的这个过于复杂但又简单的方法。。。也许有人会发现有用的东西。

/*Creates a new element - By Jamin Szczesny*/
function _new(args){
    ele = document.createElement(args.node);
    delete args.node;
    for(x in args){ 
        if(typeof ele[x]==='string'){
            ele[x] = args[x];
        }else{
            ele.setAttribute(x, args[x]);
        }
    }
    return ele;
}

/*You would 'simply' use it like this*/

$('body')[0].appendChild(_new({
    node:'div',
    id:'my-div',
    style:'position:absolute; left:100px; top:100px;'+
          'width:100px; height:100px; border:2px solid red;'+
          'cursor:pointer; background-color:HoneyDew',
    innerHTML:'My newly created div element!',
    value:'for example only',
    onclick:"alert('yay')"
}));
