Question

您好我正在尝试在html表上进行动态过滤，一般情况下工作但是我无法在字符串中移动单引号，我在php中也试过了addslashes（）也在javascript中使用regex replace（）但是没有任何作用.. 。不知道我是否需要更改过滤器逻辑这是完整的javascript代码，但我认为问题出在selectField更改函数函数中：

$(document).ready(function(){ 
function addRemoveClass(theRows){

    theRows.removeClass("odd even");
    theRows.filter(":odd").addClass("odd");
    theRows.filter(":even").addClass("even");

}   

var selVal='';

var rows=$('#myTable tbody tr');

addRemoveClass(rows);


$("#selectField").on("change",function() {
    $('table').show();
    var selection = $(this).val();
    var dataset = $('#myTable tbody').find('tr');
    dataset.show();
    // filter the rows that should be hidden
    if(selection!="All"){
        //selection=selection.replace(/'/g, '"');
        selection = selection.replace(/'/g, "\\'");
        if(selVal==="First_Name"){
            dataset.filter(function(index, item) {
            //return $(item).find('td:nth-child(1)').text().split(',').indexOf(selection) === -1;
            return $(item).find('td:nth-child(1)').text().indexOf(selection) === -1;
            }).hide();
        } else if(selVal==="Surname"){
            dataset.filter(function(index, item) {  
            return $(item).find('td:nth-child(2)').text().indexOf(selection)=== -1;
            }).hide();
        }
        else if(selVal==="Address"){
            dataset.filter(function(index, item) {
            return $(item).find('td:nth-child(3)').text().indexOf(selection) === -1;
            }).hide();
        }else{
            dataset.show();
        }
    } else{
        dataset.show();     
    }
});



$("#selectCat").on("change",function(){
    var e = document.getElementById("selectCat");
    var strUser = e.options[e.selectedIndex].value;
    selVal=strUser;
    $("#selectField").empty();
    //$("#mytBody tr").empty();
    var selected = this.value;
    if(selected !="NoCategory"){
        $.post('process.php', {category:this.value}, function(data) {
                data = $.parseJSON(data);

                    var al='All'
                    var options = "";
                        options += "<option value=All selected>All</option>";
                $("#selectField").append(options);

                    options = "";
                    for (var i = 0; i < data.length; i++) {                         
                        //data[i] = data[i].replace(/'/g, "\\'");
                        options += "<option value='" + data[i] + "'>" + data[i] + "</option>";
                        //options += "<option value='" + data[i].toLowercase() + "'>" + data[i] + "</option>";
                    }
                $("#selectField").append(options);
            return false; //prevent from reloading the page
        });

    }else{
        rows.show();
        addRemoveClass(rows);
    }

});
});

这是我正在使用的html文件中的代码：

<meta charset="UTF-8">
<script type="text/javascript" src="jquery-3.1.0.js"></script>
<script type="text/javascript" src="filter.js"></script>

                    Filter by Selected Category

                </div>  
                <table id="myTable">

                    <thead>

这是我尝试使用单引号

过滤名称时的结果 O'Reilly上的

过滤器会让每个人的名字都以“O”开头，因为名字中的单引号会在“O”之后剪切字符串，因此Index of returns返回1次

在jquery中检查我的评论。

Demo

这是我在演示中使用的html：

<div class="optionDiv">
    Filter by Category
    <select id="selectCat">
        <option value="NoCategory">NoCategory</option>
        <option value="First_Name">First_Name</option>
        <option value="Surname" selected>Surname</option>
        <option value="Address">Address</option>
    </select>
    Filter by Selected Category
    <select id="selectField">
        <option value="All" selected>All</option>   
        <option value="O'Reilly">O'Reilly</option>
    </select>
</div>  
<table id="myTable">
    <thead> 
        <tr id=HeadRow><th>First_Name</th><th>Surname</th><th>Address</th><th>ID</th></tr>                      
    </thead>  
    <tbody> 
        <tr><td>Michael</td><td>O'Reilly</td><td>581 Beech Street, Lincoln, NE 68506</td><td>246</td></tr>
        <tr><td>Della</td><td>Austin'</td><td>376 Washington Street, Pompano Beach, FL 33060</td><td>247</td></tr>
        <tr><td>Hector</td><td>Hopkins</td><td>442 College Street, East Brunswick, NJ 08816</td><td>248</td></tr>
        <tr><td>Terrance</td><td>Garza'</td><td>737 Route 1, Mahwah, NJ 07430</td><td>249</td></tr>
        <tr><td>Melvin</td><td>Boyd'</td><td>525 Olive Street, Derby, KS 67037</td><td>250</td></tr>
        <tr><td>Kimberly</td><td>Alvarez'</td><td>269 Olive Street, Redondo Beach, CA 90278</td><td>251</td></tr>
        <tr><td>Eleanor</td><td>Steele'</td><td>447 Canal Street, Goose Creek, SC 29445 </td><td>252</td></tr>
        <tr><td>Elsa</td><td>Osborne'</td><td>894 Pheasant Run, Pottstown, PA 19464</td><td>253</td></tr>
        <tr><td>Cameron</td><td>Huff'</td><td>416 Parker Street, Riverdale, GA 30274</td><td>254</td></tr>
        <tr><td>Essie</td><td>Ray'</td><td>539 Devon Court, Woodhaven, NY 11421</td><td>255</td></tr>
        <tr><td>I'Am</td><td>TheBest</td><td>MyStreet 75</td><td>256</td></tr>
        <tr><td>Bilbo</td><td>Baggins</td><td>Shire</td><td>257</td></tr>
        <tr><td>Larry</td><td>I'Connol</td><td>Larrys's Street 45</td><td>258</td></tr>
        <tr><td>Martin</td><td>O'Bannon</td><td>Martins's Street, 56</td><td>259</td></tr>
    </tbody>
</table>

这是jquery：

function addRemoveClass(theRows){
    theRows.removeClass("odd even");
    theRows.filter(":odd").addClass("odd");
    theRows.filter(":even").addClass("even");
}   
var selVal='';
var rows=$('#myTable tbody tr');
addRemoveClass(rows);
$("#selectField").on("change",function() {
    $('table').show();
    var selection = $(this).val();
    var dataset = $('#myTable tbody').find('tr');
    var selVal = $('#selectCat').val();  // Mick added this
    dataset.show();
    // filter the rows that should be hidden
    if(selVal!="All"){  // Mick added this
    // if(selection!="All"){  // Mick removed this
        console.log(selection+' & '+selVal);  // Mick added this
        // Mick says no escaping needed
        //selection=selection.replace(/'/g, '"');
        //selection = selection.replace(/'/g, "\\'");
        if(selVal=="Surname"){
            dataset.filter(function(index, item) {  
                console.log(index+' & '+item+' & '+selection);  // Mick added this
                return $(item).find('td:nth-child(2)').text().indexOf(selection)=== -1;
            }).hide();
        }else{
            dataset.show();
        }
    }else{
        dataset.show();     
    }
});

在javascript / php中移动单引号
