如果文本节点的位置索引在其兄弟节点中是固定的，则可以使用

$('parentselector').contents().eq(index).text()

使用一个额外的条件来检查innerHTML和innerText是否相同。只有在这种情况下，才需要替换文本。

$(function() {
$('body *').each(function () {
    console.log($(this).html());
    console.log($(this).text());
    if($(this).text() === "Search" && $(this).html()===$(this).text())  {
        $(this).html("Find");
    }
})
})

不确定有多灵活或多少情况下，你需要它覆盖，但对于你的例子，如果文本总是出现在第一个HTML标签之前-为什么不只是在第一个标签上分割内部HTML，并采取前者:

$('#listItem').html().split('<span')[0]; 

如果你需要更宽一点

$('#listItem').html().split('<')[0]; 

如果你需要两个标记之间的文本，比如在一件事之后，但在另一件事之前，你可以做一些像(untesting)这样的事情，并使用if语句使它足够灵活，有一个开始或结束标记，或两者都有，同时避免null ref错误:

var startMarker = '';// put any starting marker here
var endMarker = '<';// put the end marker here
var myText = String( $('#listItem').html() );
// if the start marker is found, take the string after it
myText = myText.split(startMarker)[1];        
// if the end marker is found, take the string before it
myText = myText.split(endMarker)[0];
console.log(myText); // output text between the first occurrence of the markers, assuming both markers exist.  If they don't this will throw an error, so some if statements to check params is probably in order...

I generally make utility functions for useful things like this, make them error free, and then rely on them frequently once solid, rather than always rewriting this type of string manipulation and risking null references etc. That way, you can re-use the function in lots of projects and never have to waste time on it again debugging why a string reference has an undefined reference error. Might not be the shortest 1 line code ever, but after you have the utility function, it is one line from then on. Note most of the code is just handling parameters being there or not to avoid errors :)

例如:

/**
* Get the text between two string markers.
**/
function textBetween(__string,__startMark,__endMark){
    var hasText = typeof __string !== 'undefined' && __string.length > 0;
    if(!hasText) return __string;
    var myText = String( __string );
    var hasStartMarker = typeof __startMark !== 'undefined' && __startMark.length > 0 && __string.indexOf(__startMark)>=0;
    var hasEndMarker =  typeof __endMark !== 'undefined' && __endMark.length > 0 && __string.indexOf(__endMark) > 0;
    if( hasStartMarker )  myText = myText.split(__startMark)[1];
    if( hasEndMarker )    myText = myText.split(__endMark)[0];
    return myText;
}

// now with 1 line from now on, and no jquery needed really, but to use your example:
var textWithNoHTML = textBetween( $('#listItem').html(), '', '<'); // should return text before first child HTML tag if the text is on page (use document ready etc)

试试这个:

$('#listItem').not($('#listItem').children()).text()

jQuery.fn.ownText = function () {
    return $(this).contents().filter(function () {
        return this.nodeType === Node.TEXT_NODE;
    }).text();
};

对我来说，这似乎是一个过度使用jquery的例子。下面将抓取文本，忽略其他节点:

document.getElementById("listItem").childNodes[0];

你需要修剪它，但它能让你在一个简单的线条中得到你想要的。

EDIT

上面将获得文本节点。要得到实际的文本，使用这个:

document.getElementById("listItem").childNodes[0].nodeValue;
