Question

我能够在找到第一个单词时搜索并替换字符串，我可以匹配前2个或3个单词，还是可以匹配完整的句子，包括间距

// Enlish text = "Name is not valid."
if ($(this).text().match("^Current")) {
    $(this).text('Nom est pas valable.');
}

Answer 1

应该有效，请参见下面的基本示例：

＆＃13;

var example1 = "Current foo bar some extra test here";
var example2 = "foo Current bar";

if (example1.match("^Current foo bar")) 
    alert('1 ---- Nom est pas valable.');

if (example2.match("^Current")) 
    alert('2 ---- Nom est pas valable.');

＆＃13;

^匹配数据的开头。

        Interval, in milliseconds:
        <input type="number" class="form-control" ng-model="myInterval">
        <br />Enter a negative number or 0 to stop the interval.

如果您想检查数据的开头，请使用

var text = "Current in this world, Current in Current bar in it for example Current in Current for and again Current in world";

g用于全局搜索。这意味着它将匹配所有出现。

text.match(/^Current in this world/).

我怎么能比较jquery匹配中的字符串
