我的主要问题是,如何区分哪个下拉框已更改? 本质上,我具有下拉框/组合框的HTML代码,该代码由JS中的JSON文件填充。
<select id="filterCountry">
<option value="0">All Countries</option>
</select>
<select id="filterBrowser">
<option value="0">All Browsers</option>
</select>
<select id="filterOS">
<option value="0">All Operating System</option>
</select>
我的jQuery代码现在与此类似。
$("#filterBrowser, #filterOS, #filterCountry").change(function(e){
alert("Something has been changed " + this.value);
// Ugly pseudocode but something along the lines of...
if(("#filterBrowser").change) {
console.log("the browser drop down was changed");
} else if (("#filterOS").change) {
console.log("The OS drop down changed");
} else if(("#filterCountry").change) {
console.log("The country drop down was changed")
}
});
答案 0 :(得分:0)
您可以获得引发事件的元素的ID。例如:
if(this.id === 'filterBrowser') {
//...
}
