Question

我有这个jquery代码来搜索文本并替换它。我有一个datalist里面的div。此jquery将仅编辑列表中的前两个项目。我怎么能让它搜索该文本的所有列表和/或整个页面并替换它。

  <script type="text/javascript">
        $(function () {
            var elem = $("#details").html(); // fetch the HTML from the #foo ID
            var elem2 = $("#details2").html();
            var bath = "Bathroom"; // text to replace 
            var bedroom = "Bedroom"; // text to replace
            var replaceBath = "Bath"; // text to replace with
            var replaceBed = "Bed"; // text to replace with
            elem = elem.replace(bath, replaceBath); // replace & update string
            elem = elem.replace(bedroom, replaceBed); // replace & update string
            elem2=elem2.replace(bath,replaceBath);
            elem2=elem2.replace(bedroom,replaceBed);
            $("#details").html(elem); // apply updated string to #foo
            $("#details2").html(elem2);
            alert(elem2);


        });
    </script>

我在数据主义者中有这两个div。

 <div class="col-md-3">
                    <div class="details" id="details1"><%#DataBinder.Eval(Container.DataItem,"Bedrooms", "{0:n0}") %>  <%#DataBinder.Eval(Container.DataItem,"Bathrooms", "{0:n1}") %> Single Family Home</div>
                  </div>

 <div class="col-md-3">
                    <div class="details" id="details2"><%#DataBinder.Eval(Container.DataItem,"Bedrooms", "{0:n0}") %>  <%#DataBinder.Eval(Container.DataItem,"Bathrooms", "{0:n1}") %> Single Family Home</div>
                  </div>

Answer 1

jQuery Contains() selector应该能够帮助识别页面上包含搜索字符串的任何元素。通过使用*选择器，我们告诉jQuery查看DOM中的每个标记。

var matches = $( "*:contains(" + stringToLookFor + ")" );

Answer 2

使用以下各项尝试以下内容：

$(function () {

    var bath = "Bathroom"; // text to replace 
    var bedroom = "Bedroom"; // text to replace
    var replaceBath = "Bath"; // text to replace with
    var replaceBed = "Bed"; // text to replace with
    $(".details").each(function(){
        var elem = $(this).html().replace(bath, replaceBath).replace(bedroom,replaceBed);
        $(this).html(elem);
    });

});
