在下面的脚本中,我需要更改jQuery each(),以便它不是使用泛型类,而是从目标元素#customfield_11071开始,然后爬到最近的“活动窗格”父元素( .active-pane#tab-5)并且只将带有class =“text.long-field”的子元素输入传递给每个?
我认为通过将#tab-5直接传递到每个它会执行它,但是它拾取与tab-5父容器之外的类匹配的文本输入字段并将它们添加到总容器中,从而产生一个糟糕的计算。
jQuery(document).ready(function(){
//iterate through each textboxes and add keyup
//handler to trigger sum event
jQuery("#tab-5 input.text.long-field").each(function() {
jQuery(this).keyup(function(){
calculateSum();
});
});
});
function calculateSum() {
var sum = 0;
//iterate through each textboxes and add the values
jQuery("#tab-5 input.text.long-field").each(function() {
//add only if the value is number
if(!isNaN(this.value) && this.value.length!=0 && this.id !== "customfield_11071") {
sum += parseFloat(this.value);
}
});
//.toFixed() method will roundoff the final sum to 2 decimal places
jQuery("#customfield_11071").val(sum.toFixed(2));
}

UPDATE:或者,也许我可以将特定的id集合填充到数组中并将其传递给each()?
答案 0 :(得分:0)
您的脚本可以正常工作。见http://jsfiddle.net/jEEKL/。如果您使用此jQuery("#tab-5 input.text.long-field")
jQuery选择器获取额外字段,请检查您的源是否有重复的标签ID。
