如何使用Materialize在onAutocomplete上获取元素属性 [英] How to get element attributes onAutocomplete with Materialize
问题描述
我在3个输入元素上使用了相同的Materialize Autocomplete.然后在onAutocomplete()上,我需要获取使用自动完成功能的元素的ID,以便可以在正确的位置填充数据.所以我想知道它是 autocomplete-input1
还是 autocomplete-input2
.如何使用纯JavaScript做到这一点?
I am using the same Materialize Autocomplete on 3 input elements. Then on onAutocomplete() I need to get the ID of the element the autocomplete was used on so I can populate data in the right place. So I want to know if it was either autocomplete-input1
or autocomplete-input2
. How can I do that in pure javascript?
<div class="col s12">
<div class="row">
<div class="input-field col s6">
<input type="text" id="autocomplete-input1" class="autocomplete" autocomplete="off">
<label for="autocomplete-input1">Input1: Type my name - Radek</label>
</div>
<div class="input-field col s6">
<input type="text" id="autocomplete-input2" class="autocomplete" autocomplete="off">
<label for="autocomplete-input2">Input2: Type my name - Radek</label>
</div>
</div>
</div>
我想知道用户输入的元素ID并使用自动完成功能.javascript代码将成为onAutocomplete函数的一部分.我尝试了几种选择,但都没有用.
I want to know the ID of element user typed something and use the autocomplete. The javascript code would be part of the onAutocomplete function. I tried few options but none worked.
$(function () {
$('input.autocomplete').autocomplete({
data: {
"Radek Surname <br> radeksurname@ymail.com": null,
"Radek": null,
"Radoslav": 'http://placehold.it/250x250'
},
onAutocomplete: function(txt) {
console.log(this.getAttribute("id"));
console.log(this.id);
console.log(this.innerHTML);
console.log(this.innerText);
console.log(this.outerHTML);
},
limit: 20,
});
});
您可以使用此 jsFiddle 和..
