jquery $.each 中的 appendTo() 似乎导致闪烁 [英] appendTo() inside $.each in jquery seems to cause flicker

问题描述

appendTo() 在 $.each.... 中时会导致闪烁

appendTo() causes flicker when it is inside $.each....

$.each(jsob.Table, function(i, employee) {
                $('<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>').appendTo('#ResultsDiv');
            });

现在我将每个新 div 附加到 #ResultsDiv inside$.each 这样做是好还是坏...如果是坏的可以做些什么来使我的 div 在循环之后 appendTo() 以便我不会闪烁....

Right now i am appending every new div to #ResultsDiv inside$.each is it good/bad to do so... If it is bad What can be done to make my divs appendTo() after the loop so that i it wont flicker....

(基于答案)

var divs = '';
            $.each(jsob.Table, function(i, employee) {
                divs += '<div class="resultsdiv"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>';
            });
            $("#ResultsDiv").append(divs);

但这也不能阻止闪烁...

But that too doesn't stop the flicker...

推荐答案

追加到 DOM 是一项非常昂贵的任务，尤其是在循环中.您应该尝试将所有结果添加到一个字符串中，然后在每个循环后添加一个:

Appending to the DOM is a very expensive task to perform especially in a loop. You should try to add all your results to a string and then do one append after the each loop:

var dataToAppend = '';
$.each(jsob.Table, function(i, employee) {
            dataToAppend += '<div class="resultsdiv" style="display:none"><br /><span class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>';
        });
$('#ResultsDiv').append(dataToAppend);
$('#ResultsDiv').removeAttr('style');

.append() 和 .appendTo() 方法执行相同的任务.主要区别在于特定于语法的内容和目标的位置.

The .append() and .appendTo() methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target.

还可以尝试将 display:none 添加到 resultsdiv 中，然后在执行附加后删除该样式以查看是否有助于消除闪烁.

Also try adding display:none to the resultsdiv and then remove that style after you perform the append to see if that helps with the flickering.
