问题描述



我使用findandreplace这是一个迷你插件,它是:

 函数findAndReplace(searchText,replacement,searchNode){
if(!searchText || typeof replacement ==='undefined') {
alert(请在字段中输入一些文字);
return;
}
var regex = typeof searchText ==='string'?
new RegExp(searchText,'g'):searchText,
childNodes =(searchNode || document.body).childNodes,
cnLength = childNodes.length,
excludes ='的HTML,头,风格,标题,链接,元,脚本对象,IFRAME;
while(cnLength--){
var currentNode = childNodes [cnLength];
if(currentNode.nodeType === 1&&
(excludes +',')。indexOf(currentNode.nodeName.toLowerCase()+',')=== -1){
arguments.callee(searchText,replacement,currentNode);

if(currentNode.nodeType!== 3 ||!regex.test(currentNode.data)){
continue;

var parent = currentNode.parentNode,
frag =(function(){
var html = currentNode.data.replace(regex,replacement),
wrap =(document.createElement('div'),
frag = document.createDocumentFragment();
wrap.innerHTML = html;
while(wrap.firstChild){
frag.appendChild (wrap.firstChild);
}
return frag;
})();
parent.insertBefore(frag,currentNode);
parent.removeChild(currentNode);




$ b现在我需要查找按钮来做一个找到每个项目的单独的JS。我已经这样做了,它为每个找到的项目添加了一个不同的随机ID。现在我只需要JS。当我完成了这一切,我会希望它,所以当你点击一个发现的单词,它有一个弹出式(不警报)说:替换Word:{INPUT HERE}然后它将取代只是这个词。我认为这将很酷。

我的查找代码是:

$ p $ document.getElementById('find')。onsubmit = function(){
findAndReplace(document.getElementById('fText')。value,function(hi){
var n = Math.floor(Math .random()* 9999999999);
var s = Math.floor(Math.random()* 30);
$ b $('#fade')。 id =show+ n +'style =display:none;>< / span>');
$('#show'+ n +'').html(hi);
$('body')。prepend(< script type ='text / javascript'> $('#highlight'+ n +').click(function(){$('#fade ').show();}); $('#highlight+ n +').mouseover(function(){$('#highlight+ n +').css('background','blue ');}); $('#highlight+ n +').mouseout(function(){$('#highlight+ n +').css('background','yellow');} );< / sc+ript>);
return'< span id =highlight+ n +'style =backgroun d:yellow; color:black;>'+ hi +'< / span>;

});
返回false;
};

我发现.html不能放置< script> 标签到一个文件,所以我希望有另一种方式,我可以做到这一点。
它看起来有点疯狂。 Mabye你可以看得更清楚,知道我想要什么这里



我希望有人能帮忙。谢谢。

解决方案

我在脚本的最后添加了下面的代码。它接受来自提示的输入,但它将全部取代,而不仅仅是您点击的那个。



$ $ p'$ live('click',function(){
replacePrompt = prompt('将Word替换为','{INPUT HERE}');
findAndReplace(document。 getElementById('fText')。value,function(){
return'< span class =highlight2style =background:white; color:black;>'+ replacePrompt +'< / span> ;';
});
return false;
})

也许我可以通过你的 findAndReplace 函数来解决问题。



更新:解决方案是根本不使用 findAndReplace 插件。我仍然不确定,但这可能是你想要的。

  $('span [id ^ = highlight]')。 live('click',function(){
replacePrompt = prompt('将Word替换为','{INPUT HERE}');
$(this).text(replacePrompt);
})


I'm trying to create a Find and Replace for the whole page.

I'm Using findandreplace which is a mini-plugin which is:

function findAndReplace(searchText, replacement, searchNode) {
    if (!searchText || typeof replacement === 'undefined') {
       alert("Please Enter Some Text Into the Field");
        return;
    }
    var regex = typeof searchText === 'string' ?
                new RegExp(searchText, 'g') : searchText,
        childNodes = (searchNode || document.body).childNodes,
        cnLength = childNodes.length,
        excludes = 'html,head,style,title,link,meta,script,object,iframe';
    while (cnLength--) {
        var currentNode = childNodes[cnLength];
        if (currentNode.nodeType === 1 &&
            (excludes + ',').indexOf(currentNode.nodeName.toLowerCase() + ',') === -1) {
            arguments.callee(searchText, replacement, currentNode);
        }
        if (currentNode.nodeType !== 3 || !regex.test(currentNode.data) ) {
            continue;
        }
        var parent = currentNode.parentNode,
            frag = (function(){
                var html = currentNode.data.replace(regex, replacement),
                    wrap = document.createElement('div'),
                    frag = document.createDocumentFragment();
                wrap.innerHTML = html;
                while (wrap.firstChild) {
                    frag.appendChild(wrap.firstChild);
                }
                return frag;
            })();
        parent.insertBefore(frag, currentNode);
        parent.removeChild(currentNode);
    }
}

At the moment I need the find button to make a seperate JS for each Item found. I have made it so it adds a different random ID for each found item. Now I just need the JS. When Im done with the whole this I will want it so when you click on one of the found words it has a popup(not alert) saying: "Replace Word with: {INPUT HERE}" Then it will replace just that word. I thought that would be cool.

My find code is:

document.getElementById('find').onsubmit = function() {
    findAndReplace(document.getElementById('fText').value, function(hi) {
        var n = Math.floor(Math.random() * 9999999999);
        var s = Math.floor(Math.random() * 30);

        $('#fade').after('<span id="show' + n + '" style="display:none;"></span>');
        $('#show' + n + '').html(hi);
        $('body').prepend("<script type='text/javascript'>$('#highlight" + n + "').click(function(){$('#fade').show();});$('#highlight" + n + "').mouseover(function(){$('#highlight" + n + "').css('background', 'blue');});$('#highlight" + n + "').mouseout(function(){$('#highlight" + n + "').css('background', 'yellow');});</sc" + "ript>");
        return '<span id="highlight' + n + '" style="background: yellow;color: black;">' + hi + '</span>';

    });
    return false;
};

I figured out that .html cant place <script> tags into a document so I hope there is another way I can do this. Its a little crazy looking. Mabye you can see it better and know what I want here

I hope someone can help. Thank you.

解决方案

I added the following code at the end of your script. It takes input from a prompt but it will 'replace all', not just the one that you click.

$('span[id^=highlight]').live('click', function () {
    replacePrompt = prompt('Replace Word with:','{INPUT HERE}');
    findAndReplace(document.getElementById('fText').value, function() {
        return '<span class="highlight2" style="background: white;color: black;">' + replacePrompt + '</span>';
    });
    return false;
})

Maybe I can work something out after going through your findAndReplace function..

UPDATE: A solution is to not use the findAndReplace plugin at all. I am still not sure but this is probably what you want.

$('span[id^=highlight]').live('click', function () {
    replacePrompt = prompt('Replace Word with:','{INPUT HERE}');
    $(this).text(replacePrompt);
})
