问题描述
上下文:
我需要获取TD元素中的一些动态ID,将其作为参数传递并调用一个特定的函数。
I need to get some dynamic ids that are inside a TD element, to pass it as a parameter and call an specific function.
我在TD中添加了一个类( .calcStartPrice ),这样它可以帮助我迭代它的元素:
I added a class (.calcStartPrice) to the TD, so that it helps me iterating inside its elements:
var inputEl, eventStartPrice, exchangeRate, convertedStartPriceEl, currSymbol, decimalPlaces;
jQuery(".calcStartPrice").each(function (i,e) {
jQuery(e).find('span, input').each(function (a,b) {
console.info(b.id);
});
});
当我运行此代码时,我有以下ID:
When I run this code, I have the following ids:
eventStartPrice_S20_L10140
S20_L10140_startPrice
exchangeRate_S20_L10140
curSymbol_S20_L10140
decPlaces_S20_L10140
converted_StartPrice_S20_L10140
现在,我要做的是检查id是否以eventStartPrice开头,以便我将id归于a变量。
Now, what I want to do is to check whether the id starts with eventStartPrice, for example, so that I'll attribute the id to a variable.
我尝试了什么:
var eventStartPrice;
jQuery(".calcStartPrice").each(function (i,e) {
jQuery(e).find('span, input').each(function (a,b) {
//console.info(b.id);
if (jQuery(b[id^="eventStartPrice"])) { //this is wrong!!!
eventStartPrice = b.id;
console.info(eventStartPrice);
}
});
});
但它不起作用...
如何检查第二次迭代内部如果id以某个字符串开头?
But it didn't work...How can I check inside that second iteration if the id starts with some string?
推荐答案
替换:
if (jQuery(b[id^="eventStartPrice"])) { //this is wrong!!!
使用:
if (/^eventStartPrice/.test(b.id)) {
