Question

我有一个输入字段用于输入输入文本和一个按钮。我还有一系列预定义的单词。 JSFiddle

var strArray = ["critical","normal","high","low","blood pressure","fracture"];

假设输入文字为

“患者情况危急，血压非常高低“

单击“提交”按钮，应将输入文本与数组中的所有字符串进行比较，找出匹配的单词，并显示与输出相同的文本，并以特定颜色突出显示匹配的单词。

预期输出

突出显示匹配单词的相同文字。

“患者处于严重状态且血压非常的低“

无论如何使用javascript / jQuery来实现这个目标吗？

Answer 1

使用动态正则表达式忽略大小写并且仅匹配全字匹配和[] .forEach：

var r=["critical","normal","high","low","blood pressure","fracture"],
s="the patient is in critical condition and the blood pressure is very low";

// replace each keyword in r with a mark'd replacement:
r.forEach(function(a){ 
         s=s.split(RegExp("\\b"+a+"\\b","i")).join("<mark>"+a+"</mark>");  
});

// view s after replacements:
s; // == "the patient is in <mark>critical</mark> condition and the <mark>blood pressure</mark> is very <mark>low</mark>"

您可以使用以下代码..

var strArray = ["critical", "normal", "high", "low", "blood pressure", "fracture"];
$("input[type='submit']").on('click', function (es) {
    var tmp = [];
    var stmt = $("input[type='text']").val();
    var stmt_arry = stmt.split(" ");
    $.each(strArray, function (i, vals) {
        $.each(stmt_arry, function (j, sVal) {
            if (sVal == vals) {
                stmt_arry[j] = "<b>" + sVal + "</b>";
            }
        });
    });
    var req_stmt = stmt_arry.join(" ");
    $("#result").html(req_stmt);
});
