代码将选择框选项值设置为对象 [英] code to set a select box option value as an object
本文介绍了代码将选择框选项值设置为对象的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
< select onChange =return filler(this.value);>
< option value ={'name':'rajiv',age:'40'}> a< / option>
< option value ={'name':'mithun',age:'22'}> f< / option>
< / select>
我想传递一个javascript数组或对象作为选项值。
现在它将选项值视为一个字符串。
我希望它是一个数组,以便我可以通过它来访问它。
this.value.name,this.value.age在填充函数中。
可能吗?
$你不能在值
属性中存储对象/数组,但是选项将使用jQuery 1.4.3 +自动支持json的 data - *
属性 <选择>
< option data-value ='{name:rajiv,age:40}'> a< / option>
< option data-value ='{name:mithun,age:22}'> f< / option>
< / select>
并使用 .change()
($(this).find(:
$ b
$(select)。选择)。data(value)。age);
});
in an html page i have got, i have a select box like this with values.
<select onChange="return filler(this.value);">
<option value="{'name':'rajiv',age:'40'}">a</option>
<option value="{'name':'mithun',age:'22'}">f</option>
</select>
i want to pass a javascript array or object as the option value. right now it is treating the option value as a string.
i want it to be an array so that i can access it by
this.value.name,this.value.age in the filler function.
is this possible?
解决方案
You will not be able to store objects/arrays in the value
attribute, however an option would be to use data-*
attributes which supports json automatically with jQuery 1.4.3+
<select>
<option data-value='{"name":"rajiv","age":"40"}'>a</option>
<option data-value='{"name":"mithun","age":"22"}'>f</option>
</select>
And using .change()
$("select").change(function(){
alert($(this).find(":selected").data("value").age);
});
