summary: |
|
|
|
|
|
<p>Like <code><a href="#duk_del_prop">duk_del_prop()</a></code>,
|
|
|
|
|
but the property name is given as an unsigned integer
|
|
|
|
|
<code>arr_index</code>. This is especially useful for deleting
|
|
|
|
|
array elements (but is not limited to that).</p>
|
|
|
|
|
|
|
|
|
|
<p>Conceptually the number is coerced to a string for the
|
|
|
|
|
property deletion, e.g. <code>123</code> would be equivalent to a property
|
|
|
|
|
name <code>"123"</code>. Duktape avoids an explicit coercion whenever
|
|
|
|
|
possible.</p>

example: |
|
|
|
|
|
duk_bool_t rc;
|
|
|
|
|
|
|
|
|
|
rc = duk_del_prop_index(ctx, -3, 123);
|
|
|
|
|
printf("delete obj[123] -> rc=%d\n", (int) rc);
