[英]Enable/Disable checkbox based on value of dropdown
I have an HTML table that includes a dropdown with 3 selections, Yes, No, Exempt and also a checkbox. 我有一个HTML表格,其中包含一个包含3个选择的下拉菜单,是,否,免除以及一个复选框。 I have set the value of Yes = 1, No = 0, and Exempt = 2. On page load, if the dropdown value equals 0 or 2, then the checkbox should be disabled.
我已将值设置为Yes = 1,No = 0,并且Exempt =2。在页面加载时,如果下拉值等于0或2,则应禁用该复选框。 If the dropdown value equals 1, then the checkbox should be enabled.
如果下拉值等于1,则应启用该复选框。 However, currently I have had no luck with getting the correct result.
但是,目前我并没有获得正确的结果。 I was able to get the value of the first row before, but that did not traverse through the entire table.
我能够获得之前第一行的值,但是并没有遍历整个表。
How can I traverse through the entire table to find each value of the dropdown, and also enable/disable the checkbox based on what is in the dropdown? 如何遍历整个表以查找下拉列表的每个值,以及如何基于下拉列表中的内容启用/禁用复选框?

$(document).ready(function () {
$('#billing_table tr').each(function() {
var checked = $(this).find($(".billed-select")).val();
console.log(checked);
if(checked != "1") {
$('.paid').attr('disabled', true);
} else {
$('.paid').attr('disabled', false);
}
});
});

Modified the php out to show a selected value that WOULD make it disabled. 修改了php,以显示将使其禁用的选定值。
$(document).ready(function() { // add row class, avoid headers $('#billing_table tr.row').each(function() { var checked = $(this).find(".billed-select").find("option:selected").val(); console.log("checked:",checked);// alerts 0 $(this).find('.paid').prop('disabled', (checked != "1")); }); });
