将以下内容粘贴到地址栏以测试它。
javascript: $('*:contains("I am a simple string")').each(function(){ if($(this).children().length < 1) $(this).css("border","solid 2px red") }); return false;
如果你只想获取“我是一根简单的弦”。首先将文本像这样包装在元素中。
$('*:contains("I am a simple string")').each(function(){
if($(this).children().length < 1)
$(this).html(
$(this).text().replace(
/"I am a simple string"/
,'<span containsStringImLookingFor="true">"I am a simple string"</span>'
)
)
});
function distinctNodes(search, element) {
var d, e, ef;
e = [];
ef = [];
if (element) {
d = $(":contains(\""+ search + "\"):not(script)", element);
}
else {
d = $(":contains(\""+ search + "\"):not(script)");
}
if (d.length == 1) {
e.push(d[0]);
}
else {
d.each(function () {
var i, r = distinctNodes(search, this);
if (r.length === 0) {
e.push(this);
}
else {
for (i = 0; i < r.length; ++i) {
e.push(r[i]);
}
}
});
}
$.each(e, function () {
for (var i = 0; i < ef.length; ++i) {
if (this === ef[i]) return;
}
ef.push(this);
});
return ef;
