文本框“this.value”用单引号停止 JavaScript

发布于 2024-12-01 13:13:10 字数 1145 浏览 1 评论 0原文

我无法在 JavaScript this.value 中使用单引号。双引号工作正常。我尝试使用 escape() 但它不起作用，而且我想不出使用 PHP 来解决此问题的方法，那么其他人有什么想法吗？

function editItemInCart(newValue,fieldName,itemNum,cnt) {
    //alert(newValue);
    if (count == cnt) {
        count = 0;
        jQuery.ajax({
        type:"POST",
        url: "editItem.html",
        data: "newvalue=" + escape(newValue) + "&fieldname=" + fieldName + "&itemNum=" + itemNum,
     })
     document.getElementById('status' + itemNum).innerHTML = "SAVED";
      jQuery("#status" + itemNum).show();
     setTimeout("fade_out('"+itemNum+"')", 1000);
    }
    //alert(newValue + fieldName + itemNum);
}

if ($cart['title'] != "")
        echo "<label>Title: </label> <input type=\"text\" onKeyUp=\"doEditItemInCart(this.value,'title',".$itemNum.")\" onChange=\"editItemInCart(this.value,'title',".$itemNum.")\" value=\"".htmlspecialchars($cart['title'])."\"><br />";


function doEditItemInCart(newValue,fieldName,itemNum) {
    count++;
    setTimeout("editItemInCart(escape('"+newValue+"'),'"+fieldName+"',"+itemNum+","+count+")",200);
}

I cannot get single quotes to work in JavaScript this.value. Double quotes work fine. I tried to use escape() and it didn't work and I cannot think of a way to use PHP to fix this, so does anyone else have any ideas?

function editItemInCart(newValue,fieldName,itemNum,cnt) {
    //alert(newValue);
    if (count == cnt) {
        count = 0;
        jQuery.ajax({
        type:"POST",
        url: "editItem.html",
        data: "newvalue=" + escape(newValue) + "&fieldname=" + fieldName + "&itemNum=" + itemNum,
     })
     document.getElementById('status' + itemNum).innerHTML = "SAVED";
      jQuery("#status" + itemNum).show();
     setTimeout("fade_out('"+itemNum+"')", 1000);
    }
    //alert(newValue + fieldName + itemNum);
}

if ($cart['title'] != "")
        echo "<label>Title: </label> <input type=\"text\" onKeyUp=\"doEditItemInCart(this.value,'title',".$itemNum.")\" onChange=\"editItemInCart(this.value,'title',".$itemNum.")\" value=\"".htmlspecialchars($cart['title'])."\"><br />";


function doEditItemInCart(newValue,fieldName,itemNum) {
    count++;
    setTimeout("editItemInCart(escape('"+newValue+"'),'"+fieldName+"',"+itemNum+","+count+")",200);
}

尝试一下

        jQuery.ajax({type:"POST",
            url: "editItem.html?newvalue=" + escape(newValue) + "&fieldname=" + fieldName + "&itemNum=" +   itemNum,
         })

，您似乎正在设置已保存的状态，无论 ajax 响应如何。我建议添加一个ajax成功功能
http://api.jquery.com/jQuery.ajax/

try this

        jQuery.ajax({type:"POST",
            url: "editItem.html?newvalue=" + escape(newValue) + "&fieldname=" + fieldName + "&itemNum=" +   itemNum,
         })

it also appears that you are setting the status of saved regardless of the ajax response. i suggest added an ajax success function
http://api.jquery.com/jQuery.ajax/
